• Le temps de l’écriture : genèse, durée, représentations 

  Leblay, Christophe (Jyväskylän yliopisto, 2011)

  This work focuses on writing as a process describable, registering in time and space, rather than the text. This choice is based on the theoretical and methodological assumption, that, contrary to what one might expect, ...

• Pestov identities and X-ray tomography on manifolds of low regularity 

  Ilmavirta, Joonas; Kykkänen, Antti (American Institute of Mathematical Sciences (AIMS), 2023)

  We prove that the geodesic X-ray transform is injective on scalar functions and (solenoidally) on one-forms on simple Riemannian manifolds (M, g) with g ∈ C1,1. In addition to a proof, we produce a redefinition of simplicity ...

• First-order heat content asymptotics on RCD(K,N) spaces 

  Caputo, Emanuele; Rossi, Tommaso (Elsevier, 2024)

  In this paper, we prove first-order asymptotics on a bounded open set of the heat content when the ambient space is an RCD(K, N) space, under a regularity condition for the boundary that we call measured interior geodesic ...

• A quantitative second order estimate for (weighted) p-harmonic functions in manifolds under curvature-dimension condition 

  Liu, Jiayin; Zhang, Shijin; Zhou, Yuan (Elsevier, 2024)

  We build up a quantitative second-order Sobolev estimate of lnw for positive p-harmonic functions w in Riemannian manifolds under Ricci curvature bounded from below and also for positive weighted p-harmonic functions w in ...
