Geometric Gradient Flows from Elliptic Level Sets: Normal Decomposition and Reflection Dynamics

Mohammed Barkatou, Mohamed El Morsalani

We investigate the asymptotic geometry of shifting superlevel sets generated by solutions to the elliptic Dirichlet problem in , wher…

Global Convergence of the Return Dynamics in the Class

Mohammed Barkatou, Mohamed El Morsalani

The paper studies a return map defined on domains with a fixed convex core, showing that its dynamics act like an adaptive gradient descent on the domain’s thickness function and c…

Thickness functions for elliptic level sets: gradient formulas, normal expansions, and geometric remarks

Mohammed Barkatou

We study the geometry of superlevel sets of solutions to with compactly supported in a convex core . Under the radial monoto…

Sharp existence conditions and geometric inheritance for overdetermined free boundary problems of Laplacian and bi-Laplacian type

Mohammed Barkatou, Samira Khatmi

This paper provides necessary and sufficient conditions for the existence of free boundaries in overdetermined problems for the Laplacian, and sufficient conditions for the bi-Lapl…

The Return Map in the Class : Geometry, Dynamics, and Thickness Regularity

Mohammed Barkatou, Mohamed El Morsalani

We investigate a geometric dynamical mechanism arising in the class of domains containing a fixed convex set and satisfying two geometric normals properties int…

Inverse Problems for the Return Map in the Class ( ): Reconstruction and Identifiability

Mohamed El Morsalani, Mohammed Barkatou

We analyze the inverse problem of recovering geometric information from the return map induced by a round-trip between a convex core C and an admissible domain. This process define…
