Homology exponents for H-spaces
Alain Clement, Jerome Scherer
We say that a space X admits a homology exponent if there exists an exponent for the torsion subgroup of the integral homology. Our main result states if an H-space of finite type…
Relative modular classes of Lie algebroids
Yvette Kosmann-Schwarzbach, Alan Weinstein
We study the relative modular classes of Lie algebroids, and we determine their relationship with the modular classes of Lie algebroids with a twisted Poisson structure.
On the poles of topological zeta functions
Ann Lemahieu, Dirk Segers, Willem Veys
We study the topological zeta function Z_{top,f}(s) associated to a polynomial f with complex coefficients. This is a rational function in one variable and we want to determine the…
Endomorphism rings of finite global dimension
Graham J. Leuschke
For a commutative local ring , consider (noncommutative) -algebras of the form where is a reflexive -module with nonzero free direct summand. Such al…
Factoring the Adjoint and Maximal Cohen--Macaulay Modules over the Generic Determinant
Ragnar-Olaf Buchweitz, Graham J. Leuschke
A question of Bergman asks whether the adjoint of the generic square matrix over a field can be factored nontrivially as a product of square matrices. We show that such factorizati…
The stepping stone model. II: Genealogies and the infinite sites model
Iljana Zahle, J. Theodore Cox, Richard Durrett
This paper extends earlier work by Cox and Durrett, who studied the coalescence times for two lineages in the stepping stone model on the two-dimensional torus. We show that the ge…
