Formal Languages and Automata Theory

In this work, we compared the Szilard and Control languages generated by the labeled flat splicing systems with the family of languages in the Chomsky hierarchy. It has been shown that some regular language cannot be generated as Szilard language by…

On Derivation Languages of Flat Splicing Systems

In this work, we associate the idea of derivation languages with at splicing systems and compare the languages generated as derivation languages (Szi…

Based on an upper bound of locally accessible information, we formulated a very simple necessary condition for the perfect distinguishability of a set of MES by LOCC. This necessary condition is shown to be stronger than the well-known OP condition.…

Necessary Condition for Local Distinguishability of Maximally Entangl…

The (im)possibility of local distinguishability of orthogonal multipartite quantum states still remains an intriguing question. Beyond $\mathbb{C}^{3…

Let X,Y be proper, geodesically complete CAT(-1) spaces, and let f:∂X→∂Y be a Moebius homeomorphism. Let ϕ=ϕf:GX→GY be the associated geodesic conjugacy. Given 1≤p≤∞, and a family of probability measures M={μx}x∈X on GX such that supp(μx)=T1xX for a…

Hyperbolic $p$-barycenters, circumcenters, and Moebius maps

Given a Moebius homeomorphism $f : \partial X \to \partial Y$ between boundaries of proper, geodesically complete CAT(-1) spaces $X,Y$, and a family …
