We give a criterion under which one can obtain a good decomposition (in the sense of Malgrange) of a formal flat connection on a complex analytic or algebraic variety of arbitrary …

Given a flat meromorphic connection on an excellent scheme over a field of characteristic zero, we prove existence of good formal structures after blowing up; this extends a theorem …
We prove a fundamental theorem for tropical partial differential equations analogue of the fundamental theorem of tropical geometry in this context. We extend results from Aroca et al …

This paper deals with connections on non-archimedean, especially p-adic, analytic curves, in the sense of Berkovich. The curves must be compact but the connections are allowed to …
We study the variation of the convergence Newton polygon of a differential equation along a smooth Berkovich curve over a non-archimedean complete valued field of characteristic …
We prove that the radii of convergence of the solutions of ap-adic differential equation F over an affinoid domain X of the Berkovich affine line are continuous functions on X that factorize …

We consider variational properties of some numerical invariants, measuring convergence of local horizontal sections, associated to differential modules on polyannuli over a …
The main purpose of this work is to build a refinement of Grigoriev's framework that records the valuations of the coefficients in a power series solution so that convergence information …

The first aim of this paper is to generalize the results of arXiv: 2111.03548 to the case of quasi-smooth curves, which consist on providing the link between the spectrum and the radii …
