But information theory was developed into a mature theory by Claude Shannon with no such connection to logic. A recent development in logic...

Escape probability of the super-Penrose process gr-qc astro-ph.HE hep-th We consider a head-on collision of two massive particles that move in the equatorial plane of an extremal Kerr black hole, which results in the production of two massless particles. Focusing on a typical case, where both of the colliding parti...

Color groups of colorings of $N$-planar modules math.MG math.CO A submodule of a $\mathbb{Z}$-module determines a coloring of the module where each coset of the submodule is associated to a unique color. Given a submodule coloring of a $\mathbb{Z}$-module, the group formed by the symmetries of the module that induc...

Reflection maps math.AG Given a reflection group $G$ acting on a complex vector space $V$, a reflection map is the composition of an embedding $X \hookrightarrow V$ with the orbit map $V\to\mathbb C^p$ that maps a $G$-orbit to a point. Reflection maps can be very singular, but we give tools to study them easily. We...
