## Abstract The paper introduces a new class of two parameter nonโ€overdamped operator pencils arising from evolution equations. We investigate spectral properties, including variational principles for โ€œinteriorโ€ points of the spectrum. Examples leading to pencils of the new class are given. (ยฉ 2006

We consider extremal problems 'of Tur~ type' for r-uniform ordered hypergraphs, where multiple oriented edges are permitted up to multiplicity q. With any such '(r, q)-graph' G" we associate an r-linear form whose maximum over the standard (n -1)-simplex in R" is called the (graph-) density g(G ") o
