Lattices and cohomological Mackey functors for finite cyclic p-groups
Blas Torrecillas, Thomas Weigel
For a finite cyclic p-group G and a discrete valuation domain R of characteristic 0 with maximal ideal pR the R[G]-permutation modules are characterized in terms of the vanishing o…
From Hopf algebras to tensor categories
Nicolas Andruskiewitsch, Ivan Angiono, Agustin Garcia Iglesias +2
This is a survey on spherical Hopf algebras. We give criteria to decide when a Hopf algebra is spherical and collect examples. We discuss tilting modules as a mean to obtain a fusi…
A note on the construction of finitely injective modules
Pedro A. Guil Asensio, Manuel C. Izurdiaga, Blas Torrecillas
We develop a technique to construct finitely injective modules which are non trivial, in the sense that they are not direct sums of injective modules. As a consequence, we prove th…
