Amnesty International a dénoncé mardi "un génocide en direct" commis par Israël dans la bande de Gaza, où la guerre et le blocage de l'aide humanitaire poussent la population dans une situation désespérée.

Doubling Inequality and Strong Unique Continuation for an Elliptic Transmission Problem
We investigate the Strong Unique Continuation Property (SUCP) for elliptic equations with piecewise Lipschitz coefficients exhibiting jump discontinuities across a regular interface. We prove SUCP at the interface using a doubling inequality derived from a Carleman estimate with a singular weight. This result is intended as a first step toward solving the inverse problem of estimating the size of an unknown, merely measurable, inclusion inside a conductor from boundary measurements.

Ergodic automorphisms on Kirchberg algebras
Combining the theory of extensions of C*-algebras and the Pimsner construction, we show that every countable infinite discrete group admits an ergodic action on arbitrary unital Kirchberg algebra. In the proof, we give a Pimsner construction realizing many unital subalgebras of a given unital Kirchberg algebra as the fixed point algebras of single automorphisms. Furthermore, for amenable infinite discrete groups, we show that every point-wise outer action on arbitrary unital Kirchberg algebra h…

Today's pondering: Once you start getting begbounties, does that mean you're site is easy to find and secure enough that the only thing to find are info-level issues, or are those engaging in begbounties so incompetent that info-level issues are the only thing they are able to find?
