On lifting stable diagrams in Frobenius categories
Matthias Kuenzer
Suppose given a Frobenius category E, i.e. an exact category with a big enough subcategory B of bijectives. Let_E_ := E/B denote its classical stable category. For example, we may…
On coefficient valuations of Eisenstein polynomials
M. Kuenzer, E. Wirsing
Let p > 2 be a prime, let n > m > 0. Let pi_n be the norm of zeta_{p^n} - 1 under C_{p-1}, so that Z_(p)[pi_n] | Z_(p) is a purely ramified extension of discrete valuation rings of…
On representations of twisted group rings
Matthias Kuenzer
We generalize certain parts of the theory of group rings to the twisted case. Let G be a finite group acting (possibly trivially) on a field L of characteristic coprime to the orde…
A relative Yoneda Lemma (manuscript)
Matthias Kuenzer
We construct set-valued right Kan-extensions via a relative Yoneda Lemma.
A two-box-shift morphism between Specht modules
Matthias Kuenzer
Let n geq 1, let lambda be a partition of n, let mu be a partition arising from lambda by a downwards shift of two boxes situated at the bottom of a column. We give a formula for a…
