Reduction of an elliptic curve over the rational numbers to an elliptic curve over a finite field mod p by
Ciro Santilli 40 Updated 2025-07-16
This construction takes as input:and it produces an elliptic curve over a finite field of order as output.
The constructions is used in the Birch and Swinnerton-Dyer conjecture.
To do it, we just convert the coefficients and from the Equation "Definition of the elliptic curves" from rational numbers to elements of the finite field.
For the denominator , we just use the multiplicative inverse, e.g. supposing we havewhere because , related: math.stackexchange.com/questions/1204034/elliptic-curve-reduction-modulo-p

Minimum-weight triangulation (MWT) refers to the problem of dividing a simple polygon into triangles in such a way that the total weight of the edges used in the triangulation is minimized. The "weight" of an edge can be defined in various ways depending on the context, but it commonly relates to the length of the edge in geometric scenarios.

Summary:
- overview of the formula of the BSD conjecture
- definition of elliptic curve
- domain of an elliptic curve. Prerequisite: field
- elliptic curve group. Prerequisite: group
- Mordell's theorem lets us define the rank of an elliptic curve over the rational numbers, which is the . Prerequisite: generating set of a group
- reduction of an elliptic curve from to lets us define as the number of elements of the generated finite group
Naive set theory is an informal approach to set theory that deals with the basic concepts and principles of sets without the rigorous formalism found in axiomatic set theory, such as Zermelo-Fraenkel set theory with the Axiom of Choice (ZFC). In naive set theory, a set is generally defined intuitively as a collection of distinct objects, which can be anything: numbers, symbols, points, or even other sets.
In Norse mythology, Ægir and Rán are two deities associated with the sea. Ægir is often depicted as a giant and is known for hosting elaborate feasts for the gods. Rán, his wife, is a goddess associated with the ocean who is known to ensnare sailors with her net. The "Nine Daughters of Ægir and Rán" are nine sea maidens who are said to embody different aspects of the ocean.
The parity of a permutation refers to whether the permutation is even or odd based on the number of transpositions it can be decomposed into. - A **transposition** is a permutation that swaps two elements while leaving all others unchanged. - A permutation is classified as **even** if it can be expressed as a product of an even number of transpositions, and it is classified as **odd** if it can be expressed as a product of an odd number of transpositions.
Paul Christiano is a researcher known for his work in the field of artificial intelligence (AI), particularly focused on AI safety, alignment, and the development of robust AI systems. He has contributed to discussions about how to ensure that advanced AI systems act in ways that are beneficial to humanity and align with human values. During his time at OpenAI, Paul worked on various projects related to AI alignment and safety, exploring techniques for better aligning the goals of AI with human intentions.
Relative likelihood is a statistical concept that helps compare how likely different hypotheses or models are, given some observed data. It is often used in the context of likelihood-based inference, such as in maximum likelihood estimation or Bayesian analysis. In simpler terms, relative likelihood provides a way to assess the strength of evidence for one hypothesis compared to another.
A rotary hook is a key component used in certain types of sewing machines, particularly in industrial and heavy-duty machines. Its primary function is to create a stitch by interlocking the upper thread with the lower thread (bobbin thread). Here’s how it works: 1. **Rotation**: As the sewing machine operates, the rotary hook continuously rotates around the needle. This motion allows it to catch the upper thread at the right moment as the needle penetrates the fabric.
The Society of Tribologists and Lubrication Engineers (STLE) is a professional organization that focuses on the study and advancement of tribology and lubrication engineering. Tribology is the science and technology of friction, lubrication, and wear of interacting surfaces in relative motion. The STLE aims to foster research, education, and innovation in these fields, promoting the importance of effective lubrication and tribological systems in various industries, from automotive and aerospace to manufacturing and energy.

A Williamson amplifier is a type of audio power amplifier designed in the 1940s by British engineer Harold Stephen Williamson. It is known for its high fidelity and is notable for its use in vacuum tube audio amplification, making it popular among audiophiles and in high-quality audio applications. The Williamson amplifier features a push-pull output stage typically using vacuum tubes, which helps to reduce distortion while delivering high power.
SoaML, or Service-Oriented Architecture Modeling Language, is a modeling language designed to facilitate the specification and analysis of service-oriented architecture (SOA) systems. It provides a standardized way to represent the components, interactions, and behaviors of services in SOA, which are critical for designing and understanding large and complex systems composed of distributed services. SoaML extends the Unified Modeling Language (UML) by introducing specific constructs and diagrams that are suited for modeling services and their interrelationships.
PSRK stands for "Predictive Soave-Redlich-Kwong." It is a thermodynamic model used primarily for predicting the phase behavior of mixtures, especially in the context of fluids and gas processing. The model is based on the Soave-Redlich-Kwong equation of state, which is an improvement over the original Redlich-Kwong equation of state for better accuracy in handling non-ideal gas behavior.
The essential spectrum is a concept from functional analysis, particularly in the study of bounded linear operators on Hilbert or Banach spaces. It is a generalization of the notion of the spectrum of an operator, focusing on properties that remain invariant under compact perturbations.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
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.
