The present investigation focuses on the mathematical concept of convexity, as the main tool for the graphic construction of bounded surfaces explicitly and implicitly described, as well as the construction of unconventional ...

We examine bulk and surface bound states in the continuum (BIC), that is, square-integrable, localized modes embedded in the linear spectral band of a discrete lattice including interactions to first and second nearest ...

We study the vacuum-subtracted von Neumann entropy of a segment on a null plane. We argue that for interacting quantum field theories in more than two dimensions, this entropy has a simple expression in terms of the ...

We explicitly bound T-singularities on normal projective surfaces W with one singularity, and K-W ample. This bound depends only on K-W(2), and it is optimal when W is not rational. We classify and realize surfaces attaining ...
