Solutions in the class of measures for some hyperbolic systems of conservation laws and scalar conservation laws with discontinuous flux.
This talk will be focused on the non-classical solutions to some hyperbolic systems of conservation laws and scalar conservation laws with discontinuous flux. We use the method of vanishing pressure limit and...

Title: Completely positive maps
A linear map $\phi$ between two C* algebras $A$ and $B$ is called positive if $\phi(a)\geq 0$ for every $a\in A$, $a\geq 0$. Here, $a\geq 0$ means a is self-adjoint and the spectrum of $a$ is contained in positive real numbers. $\phi$ is said to be $n$-positive if $\phi \...

Title: Quantum zero - error communication
We will talk about the basic concept of quantum zero-error, zero-error capacity of a quantum channel and some of its properties. Then we will look at superactivation phenomenon which is exclusive to quantum setup and the quantum...

Title: Optimality of local search algorithms
In this talk, we discuss our attempts to solve an important open problem regarding Terrain Guarding: is the state-of-the-art polynomial-time approximation scheme for the problem [...
Title: State spaces of partially ordered abelian groups with an order unit
Abstract: We will talk about states and state spaces of partially ordered abelian groups with an order unit. A state on a partially ordered abelian group with order unit (G,u) is a positive homomorphism (a group homomorphism that takes positive elements to positive elements)...
