On a characterisation of perfectoid fields by Iwasawa theory
Gautier Ponsinet
We prove that the vanishing of the module of universal norms associated with a de Rham Galois representation whose Hodge-Tate weights are not all non-positive characterises the alg…
Bloch-Kato groups over perfectoid fields and Galois theory of -adic periods
Gautier Ponsinet
We relate the structure of the Bloch-Kato groups associated with a de Rham Galois representation over a perfectoid field to the Galois theory of the ring …
On Shafarevich-Tate groups and analytic ranks in families of modular forms, II. Coleman families
Maria Rosaria Pati, Gautier Ponsinet, Stefano Vigni
This is the second article in a two-part project whose aim is to study algebraic and analytic ranks in -adic families of modular forms. Let be a newform of weight , squar…
Universal norms and the Fargues-Fontaine curve
Gautier Ponsinet
We study the module of universal norms associated with a de Rham -adic Galois representation in a perfectoid field extension. In particular, we compute precisely this module whe…
On the Iwasawa invariants of Kato's zeta elements for modular forms
Chan-Ho Kim, Jaehoon Lee, Gautier Ponsinet
We study the behavior of the Iwasawa invariants of the Iwasawa modules which appear in Kato's main conjecture without -adic -functions under congruences. It generalizes the w…
On the structure of signed Selmer groups
Gautier Ponsinet
Let be a number field unramified at an odd prime and be the -cyclotomic extension of . Generalizing Kobayashi plus/minus Selmer groups for ellip…
On the Mordell-Weil ranks of supersingular abelian varieties in cyclotomic extensions
Antonio Lei, Gautier Ponsinet
Let be a number field unramified at an odd prime and be the -cyclotomic extension of . Let be an abelian variety defined over with good…
Functional equations for multi-signed Selmer groups
Antonio Lei, Gautier Ponsinet
We study the functional equation for the multi-signed Selmer groups for non-ordinary motives whose Hodge-Tate weights are and , defined by Büyükboduk and the first named aut…
