Brane structures in microlocal sheaf theory

Journal of Topology, Volume 17, Issue 1, March 2024.
Abstract Let L$L$ be an exact Lagrangian submanifold of a cotangent bundle T∗M$T^* M$, asymptotic to a Legendrian submanifold Λ⊂T∞M$\Lambda \subset T^{\infty } M$. We study a locally constant sheaf of ∞$\infty$‐categories on L$L$, called the sheaf of brane structures or BraneL$\mathrm{Brane}_L$.

Logarithmic cotangent bundles, Chern‐Mather classes, and the Huh‐Sturmfels involution conjecture

Communications on Pure and Applied Mathematics, Volume 77, Issue 2, Page 1486-1508, February 2024.
Abstract Using compactifications in the logarithmic cotangent bundle, we obtain a formula for the Chern classes of the pushforward of Lagrangian cycles under an open embedding with normal crossing complement. This generalizes earlier results of Aluffi and Wu‐Zhou.

Decrease in climatic disequilibrium associated with climate change and species abundance shifts in Mediterranean plant communities

Journal of Ecology, Volume 112, Issue 2, Page 291-304, February 2024.
The procedure developed to measure climatic disequilibrium reflects demographic behaviours, thus providing a reliable method to assess the impact of climate change on species and communities. The study demonstrates the current, rapid tracking of Mediterranean woody plant communities to climate change. This tracking results from changes in the abundance

Inverse problems and microlocal analysis [PDF]

Journées équations aux dérivées partielles, 1991
In this lecture we discuss some recent problems in inverse scattering for the two-body Schrödinger operator \(H_ v=H_ 0+v\) in \(\mathbb{R}^ n\) where \(H_ 0=-\Delta\). The main part of the presentation will be devoted to the definition of exceptional points for \(H_ v\) and a study of the geometrical properties of the set \({\mathcal E}\) of such ...

Analysis of the Energy Decay of a Degenerated Thermoelasticity System

, 2012
In this paper, we study a system of thermoelasticity with a degenerated second order operator in the Heat equation. We analyze the evolution of the energy density of a family of solutions.

Symplectic Techniques for Semiclassical Completely Integrable Systems

, 2004
This article is a survey of classical and quantum completely integrable systems from the viewpoint of local ``phase space'' analysis. It advocates the use of normal forms and shows how to get global information from glueing local pieces.
