Many faces of Born-Infeld theory
Born-Infeld theory is the non-linear generalization of Maxwell electrodynamics. It naturally arises as the low-energy effective action of open strings,

The Dual Faces of String Theory
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that, for backgrounds generated from compact

Ununfoldable Polyhedra with Convex Faces
Unfolding a convex polyhedron into a simple planar polygon is a well-studied problem. In this paper, we study the limits

Instability of quasi-liquid on the edges and vertices of snow crystals
In this paper, we show theoretically that there exists quasi-liquid on the edges and vertices of snow crystals between -4C

Nonorthogonal Polyhedra Built from Rectangles
We prove that any polyhedron of genus zero or genus one built out of rectangular faces must be an orthogonal

Reducing Thermoelastic Noise in Gravitational-Wave Interferometers by Flattening the Light Beams
In the baseline design for advanced LIGO interferometers, the most serious noise source is tiny, dynamically fluctuating bumps and valleys

Combinatorics of Non-Abelian Gerbes with Connection and Curvature
We give a functorial definition of $G$-gerbes over a simplicial complex when the local symmetry group $G$ is non-Abelian. These
