Titel: Questions and answers about Mathematical Reviews

Sammanfattning: Ever since the beginnings of the Mathematical Reviews in 1940, the journal has served the international mathematical community with up-to-date information on peer reviewed articles and books in mathematics and some very closely related fields. An editor of Mathematical Reviews Dr. Margaret Stawiska-Friedland will share her insider view of the current work and aims of this influential publication.

Titel: Tensors and entanglement in quantum physics

Sammanfattning:Tensors, or multiarrays with at least three indices, are ubiquitous in modern applications, mainly due to data explosion. While matrices,(two indices), are well understood and widely used, tensors pose theoretical and numerical challenges. Tensors also arise naturally in quantum physics, when dealing with multi-particle systems. In this talk, for general mathematical audience, we will describe several fundamental results and problems in tensors: tensor ranks, low rank approximation of tensors, spectral and nuclear norm of tensors, and their relation to the entanglement and nonseparability in quantum information theory.
