Friedman's SSCG (Stochastic Simulation and Control Game) function is a concept used in the context of economics and decision theory, particularly related to dynamic programming and optimal control. The SSCG function is often utilized to model and analyze strategic interactions and decisions under uncertainty. The exact formulation of the SSCG function can vary, but it typically involves aspects of stochastic processes, where outcomes depend not only on the current state and action but also on random events that can influence future states.

Theorems in plane geometry are propositions or statements that can be proven based on axioms, definitions, and previously established theorems. Plane geometry deals with flat, two-dimensional surfaces and includes the study of points, lines, angles, shapes (such as triangles, quadrilaterals, and circles), and their properties.

Pappus's centroid theorem, named after the ancient Greek mathematician Pappus of Alexandria, is a principle concerning the geometry of figures in relation to their centroids (or centroids). It actually consists of two related theorems, often referred to as Pappus's centroid theorems.

The Petersen–Morley theorem is a result in graph theory that concerns the structure of certain types of graphs. It states that for every sufficiently large graph, if it contains no complete subgraph \( K_n \) of size \( n \), then the graph can be colored with \( n-1 \) colors such that no two adjacent vertices share the same color. The theorem is particularly relevant when discussing the properties of planar graphs and colorability.

The Riemannian Penrose inequality is a result in differential geometry and general relativity that relates the total mass of a Riemannian manifold with boundary to the area of its boundary. It is an extension of the classical Penrose inequality, which is a key result in the theory of general relativity regarding the mass of gravitational systems.

The term "2π theorem" doesn't refer to a widely recognized theorem in mathematics or physics by that name. However, it might be associated with concepts involving the number \(2\pi\), which frequently appears in contexts related to circles, trigonometry, and periodic functions.

The Federer-Morse theorem is a result in geometric measure theory that relates to the study of properties of measures in Euclidean space. Specifically, it deals with rectifiable sets and their measures, providing a foundational understanding of how these sets can be characterized and analyzed.

Jørgensen's inequality is a result in the field of functional analysis, particularly concerning the relationships between norms in Banach spaces. Specifically, Jørgensen's inequality pertains to the estimates of certain linear operators and is often discussed in the context of submartingales, Brownian motion, and processes in probability theory.

The Thom conjecture, proposed by mathematician René Thom in the 1950s, relates to topology and singularity theory. Specifically, it concerns the structure of non-singular mappings between manifolds and the conditions under which certain types of singularities can occur. The conjecture asserts that every real-valued function defined on a manifold can be approximated by a function that has a certain type of "generic" singularity.

Ribet's theorem is a fundamental result in number theory related to the Taniyama-Shimura-Weil conjecture, which is a key element in the proof of Fermat's Last Theorem. The theorem, proved by Ken Ribet in 1986, establishes a crucial connection between elliptic curves and modular forms.

Lindström's theorem is a significant result in model theory, a branch of mathematical logic that deals with the relationships between formal languages and their interpretations, or models. Formulated by Per Lindström in the 1960s, the theorem characterizes the logical systems that enjoy certain completeness and categoricity properties, specifically those known as the "Lindström properties.

Zeckendorf's theorem states that every positive integer can be uniquely represented as a sum of one or more distinct non-consecutive Fibonacci numbers.

In set theory, the term "lemma" generally refers to a proven statement or proposition that is used as a stepping stone to prove other statements or theorems. In mathematical writing, authors often introduce lemmas to break down complex proofs into smaller, more manageable pieces. A lemma may not be of primary interest in itself, but it helps to establish the truth of more significant results.

Computational learning theory is a subfield of artificial intelligence and machine learning that focuses on the study of algorithms that learn from and make predictions or decisions based on data. It provides a theoretical framework to understand the capabilities and limitations of learning algorithms, often examining issues such as the complexity of learning tasks, the types of data, and the models employed for prediction.

The Bing metrization theorem is a result in the field of topology, specifically in the area concerning the metrization of topological spaces. It provides a condition under which a topological space can be given a metric that generates the same topology. Formulated by the mathematician R. Bing in the mid-20th century, the theorem states that if a topological space is second countable and Hausdorff, then it can be metrized.

Janiszewski's theorem is a result in the field of topology, specifically concerning the properties of certain kinds of topological spaces. It deals with the concept of continuity and compactness in the context of mapping spaces.

Rewriting systems are a formal computational framework used for defining computations in terms of transformations of symbols or strings. They consist of a set of rules that describe how expressions can be transformed or "rewritten" into other expressions. These systems are foundational in various areas of computer science and mathematical logic, particularly in the fields of term rewriting, functional programming, and automated theorem proving.

The Sphere Theorem is a result in differential geometry that describes the geometric properties of manifolds with certain curvature conditions. Specifically, it pertains to the behavior of Riemannian manifolds that have non-negative sectional curvature. The Sphere Theorem states that if a Riemannian manifold has non-negative sectional curvature and is simply connected, then it is homeomorphic to a sphere.

The Clark–Ocone theorem is a fundamental result in the theory of stochastic calculus and financial mathematics, particularly in the context of stochastic processes. This theorem provides a way to express a certain class of random variables (specifically, adapted, or predictable functionals of a process) in terms of an integral with respect to a martingale and a stochastic integral.

In computer science, "logic" typically refers to a formal system of reasoning that is used to derive conclusions and make decisions based on given premises. It is foundational to various disciplines within computer science, including programming, artificial intelligence, databases, and more. Here are some key areas where logic plays a crucial role: 1. **Boolean Logic**: - Boolean logic uses binary values (true/false or 1/0) and basic operations like AND, OR, and NOT.
