Optimization over Degree Sequences of Graphs
Optimization over Degree Sequences
It is shown that deciding if a given sequence is the degree sequence of a 3-hypergraph is NP-complete, thereby solving a 30 year long open problem and implying that optimization over hypergraphs is hard already for simple concave functions.

This paper is concerned with a matrix A of m rows and n columns, all of whose entries are 0's and l's. Let the sum of row i of A be denoted by r i (i = 1, … , m) and let the sum of column i of A be
Minconvex Factors of Prescribed Size in Graphs
A polynomial algorithm is provided that determines for any given undirected graph G=(V,E)$, positive integer $k$, and convex functions $f_v:\mathbb{N}\rightarrow\ mathbb{R}$ ($v\in V$) a subgraph of edges that minimizes f_v(d_H(v)$, where d_H (v) is the degree of v in $H$.
Inequalities: Theory of Majorization and Its Applications
Although they play a fundamental role in nearly all branches of mathematics, inequalities are usually obtained by ad hoc methods rather than as consequences of some underlying "theory of
