Max-semistability: a survey

Abstract. In the classical limit theory for normalized sums of independent random variables we change the operation ”sum” by the operation “maximum”. How does it change the classical structure of the limit probability laws? The max-model enriches Probability Theory with interesting non-classical phenomena. Several of them will be discussed here. As an example for characterizing a limit class of...

On the semistability of instanton sheaves over certain projective varieties

We show that instanton bundles of rank r ≤ 2n − 1, defined as the cohomology of certain linear monads, on an n-dimensional projective variety with cyclic Picard group are semistable in the sense of MumfordTakemoto. Furthermore, we show that rank r ≤ n linear bundles with nonzero first Chern class over such varieties are stable. We also show that these bounds are sharp. 2000 MSC: 14J60; 14F05

Semistability of Frobenius Direct Images

— Let X be a smooth projective curve of genus g ≥ 2 defined over an algebraically closed field k of characteristic p > 0. Given a semistable vector bundle E over X, we show that its direct image F∗E under the Frobenius map F of X is again semistable. We deduce a numerical characterization of the stable rank-p vector bundles F∗L, where L is a line bundle over X. Résumé (Semi-stabilité des images...

Semistability of Nonlinear Impulsive Systems with Delays

This paper is concerned with the stability analysis and semistability theorems for delay impulsive systems having a continuum of equilibria. We relate stability and semistability to the classical concepts of system storage functions to impulsive systems providing a generalized hybrid system energy interpretation in terms of storage energy. We show a set of Lyapunov-based sufficient conditions f...

Postnikov-Stability versus Semistability of Sheaves

We present a novel notion of stable objects in a triangulated category. This Postnikov-stability is preserved by equivalences. We show that for the derived category of a projective variety this notion includes the case of semistable sheaves. As one application we compactify a moduli space of stable bundles using genuine complexes via Fourier-Mukai transforms. MSC 2000: 14F05, 14J60, 14D20
