The subset sum problem for finite abelian groups
Michiel Kosters
Let G be a finite abelian group. For g in G and i an integer we define N(i,g) to be the number of subsets of G of size i which sum up to g. We will give a short proof, using charac…

Anisotropy and the integral closure
Michiel Kosters
Let K be a number field and let A be an order in K. The trace map from K to Q induces a non-degenerate symmetric bilinear form <,>: B x B \to Q/Z where B is a certain finite abelia…

Anisotropic modules over artinian principal ideal rings
Michiel Kosters
Let V be a finite-dimensional vector space over a field k and let W be a 1-dimensional k-vector space. Let < , >: V x V \to W be a symmetric bilinear form. Then < , > is called ani…
