A "free lattice" typically refers to a type of lattice in the context of lattice theory, a branch of mathematics that studies ordered sets and their properties. In lattice theory, a lattice is a partially ordered set in which any two elements have a unique supremum (least upper bound, also known as join) and an infimum (greatest lower bound, or meet).
A cutting sequence, particularly in the context of mathematics and combinatorial optimization, refers to a specific arrangement or pattern of elements that allows for the division of a larger set into smaller, manageable subsets. While the term can apply to various fields, it is most commonly associated with graph theory, geometric constructions, and linear programming, where it may refer to processes involving partitioning objects or sequences into distinct parts.
In differential geometry and related fields, a **formally smooth map** generally refers to a type of map that behaves smoothly at a certain level, even if it may not be globally smooth in the traditional sense across its entire domain. The concept is often discussed in the context of algebraic geometry and singularity theory. To provide a clearer understanding: 1. **Smooth Maps**: A smooth map is typically a function between differentiable manifolds that is infinitely differentiable.
Hilbert's Basis Theorem is a fundamental result in algebra, particularly in the theory of rings and ideals. It states that if \( R \) is a Noetherian ring (meaning that every ideal in \( R \) is finitely generated), then any ideal in the polynomial ring \( R[x] \) (the ring of polynomials in one variable \( x \) with coefficients in \( R \)) is also finitely generated.
J-multiplicity is a concept that appears in the context of mathematical logic and model theory, particularly in the study of structures and their properties. It is often associated with the analysis of certain functions or relations over structures, and can be used to investigate how complex a particular model or theory is.
The local criterion for flatness is a condition in algebraic geometry and commutative algebra that helps determine when a morphism (or ring homomorphism) is flat. Flatness is an important property that relates to how properties of rings (or varieties) behave under base change.
The Rabinowitsch trick is a technique used in number theory, particularly in the field of algebraic number theory and in the study of polynomial divisibility. It is named after the mathematician Solomon Rabinowitsch. The trick primarily involves the manipulation of polynomials to demonstrate certain divisibility properties. Specifically, it is often applied in the context of proving that a polynomial is divisible by another polynomial under certain conditions.
In the context of commutative algebra and homological algebra, the term "weak dimension" refers to a notion that is related to the properties of modules over a ring. Specifically, the weak dimension of a module is a measure of its complexity in terms of projective resolutions.
The Mandelbrot set is a famous and visually stunning fractal named after the mathematician Benoit Mandelbrot. It is defined in the complex number plane and is created by iterating a simple mathematical formula.
The Deterministic Rendezvous Problem is a classic problem in distributed computing and algorithm design, particularly in the fields of multi-agent systems and robotics. The problem involves two or more agents (or entities) that must meet at a common point (the rendezvous point) in a distributed environment, without the use of randomization. ### Key Characteristics of the Problem: 1. **Determinism**: - The behavior of the agents is predetermined and follows a specific set of rules or algorithms.
Graph cuts is a technique used in computer vision and image processing for segmenting images into different regions or objects. It is based on graph theory and leverages the representation of an image as a weighted graph to achieve efficient segmentation. Here's a breakdown of the concept: ### Graph Representation 1. **Graph Construction**: In graph cuts, each pixel in the image is represented as a node in a graph. Edges connect these nodes, representing the relationship between pixels.
Rod Burstall is a notable Australian television and film director, producer, and writer. He is best known for his work in the Australian film industry, particularly during the 1970s and 1980s. Burstall is credited with directing several influential films, including "The Naked Bunyip" (1970) and "Stork" (1971), which contributed to the revival of the Australian film industry during that time. His works often explore themes relevant to Australian culture and society.
N. David Mermin is a prominent American physicist known for his work in theoretical condensed matter physics, quantum mechanics, and the philosophy of science. He is particularly well-known for his contributions to quantum theory, including the interpretation of quantum mechanics and research on the foundations of quantum physics. Mermin is also recognized for his clear and engaging writing style, which he has used to communicate complex scientific concepts to a broader audience. He has held academic positions at several prestigious institutions, including Cornell University.
In graph theory, a **matching** is a set of edges in a graph such that no two edges share a common vertex. In other words, it is a way of pairing the vertices of a graph such that each vertex is included in at most one edge of the matching. Here's a more detailed explanation: 1. **Vertices and Edges**: A graph consists of a set of vertices (nodes) and a set of edges (connections between pairs of vertices).
The maximum flow problem is a classic optimization problem in network flow theory, which aims to find the maximum flow that can be sent from a source node (often referred to as the "source") to a sink node (often referred to as the "sink" or "target") in a flow network. A flow network is a directed graph where each edge has a capacity representing the maximum allowable flow that can pass through that edge.
Computable topology is a subfield of mathematics that intersects the areas of general topology and computability theory. It focuses on the study of topological spaces that can be effectively manipulated using computational methods. The key idea is to determine which topological spaces and their properties can be described, analyzed, or approximated in a computable manner.
Computational criminology is an interdisciplinary field that applies computational techniques and methods to the study of crime and criminal behavior. It combines elements of criminology, computer science, data analysis, statistics, and often machine learning to analyze crime data, model criminal behavior, and predict future crime trends. Key components of computational criminology include: 1. **Data Collection and Analysis**: Gathering large sets of data related to crime, such as arrest records, surveillance footage, social media interactions, and demographic information.
Roger Scantlebury is not a widely known figure, and there may not be significant public information available about him. It's possible that he could be a person associated with a specific field, organization, or community, but without additional context, it's challenging to provide more specific information.
DNADynamo is a software application designed for the analysis and simulation of DNA sequences. It is particularly popular in the field of molecular biology and bioinformatics. The software provides tools for various tasks such as DNA sequence assembly, alignment, and visualization. It typically allows researchers to manipulate and analyze nucleotide sequences, model genetic constructs, and generate simulations for molecular interactions and behaviors. DNADynamo may also feature functionalities for gene design, cloning simulations, and other tasks pertinent to genetic engineering and synthetic biology.
TORQUE can refer to different concepts depending on the context, but here are a couple of the most common usages: 1. **Physics**: In physics, torque is a measure of the rotational force applied to an object around a pivot point or axis. It is often described mathematically as the product of the force applied and the distance from the pivot point to the line of action of the force.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
