Extremal problems related to convexity [PDF]
We consider the extremal problem of maximizing functions u in the class of real-valued biconvex functions satisfying a boundary condition ψ on a product of the unit ball with itself, with the ℓ p $\ell^{p}$ -norm. In 1986, Burkholder explicitly found the

A Survey on Extremal Problems of Eigenvalues [PDF]
Given an integrable potential q∈L1([0,1],ℝ), the Dirichlet and the Neumann eigenvalues λnD(q) and λnN(q) of the Sturm-Liouville operator with the potential q are defined in an implicit way. In recent years, the authors and their collaborators have solved

Multicoloured extremal problems [PDF]
Let \({\mathcal A}_1,\dots,{\mathcal A}_k\) be set systems on the finite underlying set \(X\) which are called colours. A finite configuration of subsets of \(X\) with \(f\) elements is multicoloured (for this set of colours) if one can find a listing \(H_1,\dots,H_f\) of the configuration and a permutation \(\pi\) of \(\{1,\dots,k\}\) such that \(H_i\)

Some problems in extremal graph theory and finite geometry [PDF]
Lazebnik, FelixThis thesis is devoted to the study of several problems in extremal graph theory and finite geometry. We study properties such as girth, spectrum, and automorphism group of various families of algebraically defined graphs. We present a new

Several problems in extremal combinatorics [PDF]
In this thesis, we study several problems from combinatorial probability theory, discrete geometry and extremal graph theory. We establish several extremal results towards our problems.

On some interconnections between combinatorial optimization and extremal graph theory [PDF]
The uniting feature of combinatorial optimization and extremal graph theory is that in both areas one should find extrema of a function defined in most cases on a finite set.

On the Existence of an Extremal Function in the Delsarte Extremal Problem [PDF]
AbstractThis paper is concerned with a Delsarte-type extremal problem. Denote by$${\mathcal {P}}(G)$$P(G)the set of positive definite continuous functions on a locally compact abelian groupG. We consider the function class, which was originally introduced by Gorbachev,$$\begin{aligned}&{\mathcal {G}}(W, Q)_G = \left\{ f \in {\mathcal {P}}(G) \cap L^
