Approximation of Minimal Functions by Extreme Functions [PDF]
In a recent paper, Basu, Hildebrand, and Molinaro established that the set of continuous minimal functions for the 1-dimensional Gomory-Johnson infinite group relaxation possesses a dense subset of extreme functions. The $n$-dimensional version of this result was left as an open question.

Theorem on the Structure of the Fractionally Linear Functional Extremal Function
The paper proves a theorem about the structure of the distribution function on which the extremum of the fractionally linear functional is reached in the presence of an uncountable number of linear constraints.

Characterizing extremal coefficient functions and extremal correlation functions
We focus on two dependency quantities of a max-stable random field $X$ on some space $T$: the extremal coefficient function $ $ which we define on finite sets of $T$ and the extremal correlation function $ (s,t)=\lim_{x \uparrow \infty} \PP(X_s \geq x \mid X_t \geq x)$.

Extremal orders of some functions connected to regular integers modulo n
Let V (n) denote the number of positive regular integers (mod n) less than or equal to n. We give extremal orders of , , , , where σ(n), ψ(n) are the sum-of-divisors function and the Dedekind function, respectively. We also give extremal orders for and ,

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.

Approximation by Extreme Functions
For a topological space \(T\) and a real normed space \(X\) let \(Y= C(T,X)\), the normed space of all \(X\)-valued bounded continuous functions on \(T\) endowed with the supremum norm. Let \(Y^{-1}=\{f\in Y:f\) does not vanish in any \(t\in T\}\). For \(f\in Y\), let \(\alpha(f)= d(f,Y^{-1})\) and let \(m(f)= \inf \{\|f(t)\|: t\in T\}\).

Time Eigenstates for Potential Functions without Extremal Points
In a previous paper, we introduced a way to generate a time coordinate system for classical and quantum systems when the potential function has extremal points.
