Title: Weyl algebra, Hyperbolic space and Noncommutative Hyperbolic plane

We propose a Weyl system represented on the Hilbert space $L^{2}(\mathbb{H}^{2}, d\mu)$ where $\mathbb{H}^{2}$ is the Hyperbolic plane and $d\mu$ is the corresponding hyperbolic measure. We give four canonical derivations on the algebra and using them propose a Lindbladian...

Title: De-Preferential Attachment Random Graphs

**Abstract:** In this talk we will introduce a new model of a growing sequence of random graphs where a new vertex is less likely to join to an existing vertex with high degree and more likely to join to a vertex with low degree. In contrast to the well studied model of...

Title: Generalized Gini Index based on U-statistics

Gini index (G), a scaled version of Gini’s mean difference (GMD), is a U-statistic of degree two. In this presentation, I will present a general approach to construct a new class of inequality measures called ad-hoc inequality measures (AIM) which are based on U-statistics of degree higher than...

Date/Time: Thursday, September 14, 2017 - 16:30 to 18:00

Speaker: Ami Viselter, University of Haifa, Israel

Title: Locally compact quantum groups: the von Neumann algebraic approach-4

Lecture series abstract: We will survey the von Neumann algebraic approach to locally compact quantum groups in the sense of Kustermans and Vaes, roughly following the treatment by Van Daele. We will begin with an intro to the theory of weights of von Neumann algebras. We will then proceed to...
