Local Ocneanu rigidity for separable algebra objects
Tinhinane Amina Azzouz, Mainak Ghosh, Sebastien Palcoux
We establish local Ocneanu rigidity for separable algebra objects in Hom-finite monoidal categories C over an algebraically closed field k. A separability morphism contracts the fi…

Spectrum of a linear differential equation over a field of formal power series
Tinhinane A. Azzouz
In this paper we associate to a linear differential equation with coefficients in the field of Laurent formal power series a new geometric object, a spectrum in the sense of Berkov…

Spectrum of a linear differential equation with constant coefficients
Tinhinane Amina Azzouz
In this paper we compute the spectrum, in the sense of Berkovich, of an ultrametric linear differential equation with constant coefficients, defined over an affinoid domain of the…
