The Bollobás–Riordan polynomial is a polynomial invariant associated with a graph-like structure called a "graph with a surface". It generalizes several concepts in graph theory, including the Tutte polynomial for planar graphs and other types of polynomials related to graph embeddings. The Bollobás–Riordan polynomial is primarily used in the study of graphs embedded in surfaces, particularly in the context of `k`-edge-connected graphs and their combinatorial properties.

The Bombieri norm is a concept encountered in the study of number theory, particularly in the context of the distribution of prime numbers and analytic number theory. Named after mathematician Enrico Bombieri, the Bombieri norm is often defined in the context of bounding sums or integrals that involve characters or exponential sums, playing a role in various results related to prime number distributions, especially in the understanding of the Riemann zeta function and L-functions.

A bracket polynomial is a type of polynomial that arises in the study of knot theory, particularly in the context of the Kauffman bracket. The bracket polynomial is a quantum invariant of knots and links, providing a way to distinguish between different knot types.

In mathematics, a "bring radical" refers to a specific type of radical expression used to solve equations involving higher-degree polynomials, especially the general quintic equation. The bring radical is derived from the "Bring-Jerrard form" of a cubic polynomial. In essence, the Bring radical is often studied in the context of finding roots of polynomials that do not have explicit formulas involving only radicals for degrees five and higher.

Cavalieri's quadrature formula, named after the Italian mathematician Bonaventura Cavalieri, is a mathematical principle used to compute the area under a curve. The formula is particularly useful in the context of integral calculus and can be seen as a way to approximate the area under a function.

Chebyshev polynomials are a sequence of orthogonal polynomials that arise in various areas of mathematics, including approximation theory, numerical analysis, and solving differential equations. There are two main types of Chebyshev polynomials: Chebyshev polynomials of the first kind and Chebyshev polynomials of the second kind. ### 1.

The Coefficient Diagram Method (CDM) is a technique used in the field of control systems and engineering, specifically for the design and analysis of robust and high-performance control systems. It provides a systematic way to create control laws by using polynomial representations of system dynamics and control objectives. ### Key Aspects of the Coefficient Diagram Method 1.

Cohn's irreducibility criterion is a test used in algebra to determine whether a certain polynomial over a field is irreducible. Specifically, it provides a criterion for a polynomial \( f(x) \) with coefficients in a field \( F \) to be irreducible over \( F \).

A complex quadratic polynomial is a polynomial of degree two that takes the form: \[ P(z) = az^2 + bz + c \] where \( z \) is a complex variable, and \( a \), \( b \), and \( c \) are complex coefficients, with \( a \neq 0 \).

In mathematics, a constant term refers to a term in an algebraic expression that does not contain any variables. It is a fixed value that remains the same regardless of the values of the other variables in the expression. For example, in the polynomial expression \( 3x^2 + 5x + 7 \), the constant term is \( 7 \), since it does not depend on the variables \( x \).

A cubic equation is a polynomial equation of degree three, which means the highest exponent of the variable (usually denoted as \( x \)) is three.

A Cyclic Redundancy Check (CRC) is an error-detecting code used to identify accidental changes to raw data. It is commonly employed in digital networks and storage devices to ensure data integrity. Here’s a breakdown of the key aspects of CRC: ### Functionality: 1. **Error Detection**: CRCs are primarily used to detect errors in data transmission or storage. They help verify that the data received is the same as the data sent.

The degree of a polynomial is defined as the highest power of the variable (often denoted as \(x\)) that appears in the polynomial with a non-zero coefficient. In other words, it is the largest exponent in the polynomial expression.

The Routh array (or Routh-Hurwitz criterion) is a systematic method used in control theory and stability analysis to determine the stability of a linear time-invariant (LTI) system by examining the characteristic polynomial of the system.

Dickson polynomials are a family of polynomials that are defined over a field, particularly in the context of finite fields and algebraic number theory. They are named after the mathematician Leonard Eugene Dickson, who studied them in the early 20th century. Dickson polynomials are denoted by \(D_n(x, y)\), where \(n\) is the degree of the polynomial and \(x\) and \(y\) are variables.

Difference polynomials are a type of polynomial that arises in the context of finite difference calculus, which deals with the differences of sequences or discrete data. They are used particularly in numerical analysis, combinatorics, and in the study of difference equations. A difference polynomial can be defined using the concept of a forward difference operator.

In mathematics, particularly in algebra, the discriminant is a specific quantity associated with a polynomial equation that provides information about the nature of its roots. The most common context in which the discriminant is discussed is in quadratic equations, which are polynomial equations of the form: \[ ax^2 + bx + c = 0 \] where \( a \), \( b \), and \( c \) are coefficients, and \( a \neq 0 \).

A divided power structure refers to a political system in which power and authority are distributed among different branches or levels of government, rather than being concentrated in a single entity. This concept is most commonly associated with federal systems, such as that of the United States, where powers are divided between national and state governments.

Division polynomials are mathematical constructs used primarily in the context of elliptic curves and their associated algebraic geometry. They serve an important role in the theory of elliptic curves, particularly regarding the addition of points on these curves. ### Context of Division Polynomials In the study of elliptic curves, a division polynomial is a polynomial that helps in defining points on the curve that are rational multiples of a given point.

The Ehrhart polynomial is a mathematical tool used in the field of combinatorial geometry, particularly in the study of polytopes and their integer points. Specifically, it counts the number of integer points in the integer dilations of a rational polytope.
