More specifically, it deals with the existence of points at which the functional attains its norm.

The Burkill integral is a mathematical concept that is part of the theory of integration, particularly in the context of functional analysis and the study of measures. Named after the British mathematician William Burkill, the Burkill integral extends the notion of integration to include more generalized types of functions and measures, particularly in the setting of Banach spaces.

"Cosmos" is a popular science book written by Carl Sagan, first published in 1980. It serves as a companion to Sagan's television series of the same name, which aired in the same year. The book explores a wide range of topics related to the universe, including the evolution of life, the development of human civilization, and the scientific method.

The Favard operator is an integral operator used in the field of functional analysis and approximation theory. It is typically associated with the approximation of functions and the study of convergence properties in various function spaces. The operator is used to construct a sequence of polynomials that can approximate continuous functions, particularly in the context of orthogonal polynomials. The Favard operator can be defined in a way that it maps continuous functions to sequences or series of polynomials by integrating against a certain measure.

FBSP (Fast Biorthogonal Spline Wavelet) is a type of wavelet that is part of the broader family of biorthogonal wavelets. Biorthogonal wavelets are characterized by having two sets of wavelet functions: one set for analysis (decomposition) and another set for synthesis (reconstruction).

The Calogero–Degasperis–Fokas (CDF) equation is a nonlinear partial differential equation that arises in mathematical physics and integrable systems. It is named after mathematicians Francesco Calogero, Carlo Degasperis, and Vassilis Fokas.

The Carleson–Jacobs theorem is a result in harmonic analysis concerning the behavior of certain functions in terms of their boundedness properties and the behavior of their Fourier transforms. It is named after mathematicians Lennart Carleson and H.G. Jacobs. The theorem essentially addresses the relationship between certain types of singular integral operators and the boundedness of functions in various function spaces, including \( L^p \) spaces.

The Chazy equation is a type of differential equation that is notable in the field of algebraic curves and modular forms. It is generally expressed in the context of elliptic functions and involves a third-order differential equation with specific properties.

The term "Chicago School" in the context of mathematical analysis typically refers to a group of researchers affiliated with the University of Chicago who have made significant contributions to various areas of mathematics, particularly in analysis, probability, and other related fields. While the phrase is also commonly associated with economics (the Chicago School of Economics), in mathematics, it reflects a style of research and pedagogical approach that emphasizes rigor, intuition, and application.

Cyclic reduction is a mathematical and computational technique primarily used for solving certain types of linear systems, particularly those that arise in numerical simulations and finite difference methods for partial differential equations. This method is particularly effective for problems that can be defined on a grid and involve periodic boundary conditions. ### Key Features of Cyclic Reduction: 1. **Matrix Decomposition**: Cyclic reduction typically involves breaking down a large matrix into smaller submatrices.

The Drinfeld upper half-plane is a mathematical construct that arises in the context of algebraic geometry and number theory, particularly in the study of modular forms and Drinfeld modular forms. It is an analogue of the classical upper half-plane in the theory of classical modular forms but is defined over fields of positive characteristic. ### Definition 1.

The Dunford-Schwartz theorem is a result in functional analysis that pertains to the theory of unbounded operators on a Hilbert space. It primarily deals with the spectral properties of these operators.

The Eden growth model, also known as the Eden process or the Eden model, is a concept in statistical physics and mathematical modeling that describes the growth of clusters or patterns in a stochastic (random) manner. It was first introduced by the physicist E. D. Eden in 1961.

The Euler–Poisson–Darboux equation is a second-order linear partial differential equation that arises in various contexts in mathematical physics and engineering. It can be seen as a generalization of the heat equation and is particularly useful in the study of problems involving wave propagation and diffusion.
