The Conway-Sloane tetralattice pairs are non-isometric
Juan Marcos Cervino, Georg Hein
Conway and Sloane constructed a 4-parameter family of pairs of isospectral lattices of rank four. They conjectured that all pairs in their family are non-isometric, whenever the pa…
Lattice invariants from the heat kernel (II)
Juan Marcos Cerviño, Georg Hein
Given an integral lattice of rank and a finite sequence of natural numbers we construct a modular form of level $N=…
Lattice invariants from the heat kernel
Juan Marcos Cerviño, Georg Hein
We derive lattice invariants from the heat flux of a lattice. Using systems of harmonic polynomials, we obtain sums of products of spherical theta functions which give new invarian…
Minimal bundles and fine moduli spaces
Georg Hein
We study sheaves E on a smooth projective curve X which are minimal with respect to the property that for all line bundles L of degree zero. We show that thes…
Postnikov-Stability versus Semistability of Sheaves
Georg Hein, David Ploog
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…
