Middle multiplicative convolution and hypergeometric equations
Nicolas Martin
Using a relation due to Katz linking up additive and multiplicative convolutions, we make explicit the behaviour of some Hodge invariants by middle multiplicative convolution, foll…

Behaviour of some Hodge invariants by middle convolution
Nicolas Martin
Following an article of Dettweiler and Sabbah, this article studies the behaviour of various Hodge invariants by middle additive convolution with a Kummer module. The main result g…
