[图书][B] p-adic Differential Equations

KS Kedlaya - 2022 - books.google.com
Now in its second edition, this volume provides a uniquely detailed study of $ P $-adic
differential equations. Assuming only a graduate-level background in number theory, the text …

Good formal structures for flat meromorphic connections, I: surfaces

KS Kedlaya - 2010 - projecteuclid.org
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 …

Good formal structures for flat meromorphic connections, II: excellent schemes

K Kedlaya - Journal of the American Mathematical Society, 2011 - ams.org
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 …

The Fundamental theorem of tropical differential algebra over nontrivially valued fields and the radius of convergence of nonarchimedean differential equations

S Mereta, F Gallinaro - arXiv preprint arXiv:2303.12124, 2023 - arxiv.org
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 …

Continuity of the radius of convergence of differential equations on p-adic analytic curves

F Baldassarri - Inventiones mathematicae, 2010 - Springer
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 …

The convergence Newton polygon of a p-adic differential equation II: Continuity and finiteness on Berkovich curves

J Poineau, A Pulita - 2015 - projecteuclid.org
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 …

The convergence Newton polygon of a p-adic differential equation I: Affinoid domains of the Berkovich affine line

A Pulita - 2015 - projecteuclid.org
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 …

Differential modules on p-adic polyannuli

KS Kedlaya, L Xiao - Journal of the Institute of Mathematics of …, 2010 - cambridge.org
We consider variational properties of some numerical invariants, measuring convergence of
local horizontal sections, associated to differential modules on polyannuli over a …

A general framework for tropical differential equations

S Mereta - 2022 - theses.hal.science
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 …

Spectrum of p-adic linear differential equations II: Variation of the spectrum

TA Azzouz - arXiv preprint arXiv:2303.06014, 2023 - arxiv.org
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 …
