Periodicity of joint-cotiles Shrey Sanadhya, PhD Ben-Gurion University of the Negev Given a finite set (a tile) F in Z^d, we say that a set A in Z^d is a co-tile of F if the collection of sets F+a, for a in A, form a tiling of Z^d. Namely, these sets are disjoint and their union in Z^d. Given a k-tuple of tiles F_1,...,F_k, we say that A is a joint co-tile of them if A is a co-tile of each F_i. In this talk I will discuss the structure of joint co-tiles in Z^d, particularly, their periodi...

Renormalization and Scattering in Relativistic Particle Theories William Klink, Professor emeritus of Mathematics, University of Iowa While there seems to be general agreement that a relativistic quantum theory is a field theory, I investigate whether it is possible to formulate a relativistic particle theory, in which the fundamental mathematical ingredients are creation and annihilation operators, rather than quantum fields. Starting with the irreps of the Poincare group, a many-particle...

A Simple, Astronomically-Based Calculation of Global Warming Climate Sensitivity, Part II Steven Spangler Professor emeritus of Physics and Astronomy, University of Iowa I will continue with a calculation to provide a rough quantitative estimate of the increase in global average temperature due to doubling of carbon dioxide.  The essence of the calculation is a simple one using an astronomically-inspired way of estimating the way in which increased carbon dioxide impedes the flow of energ...
