Although perceived by candidates and parties as important in affecting political outcomes, the link between spending and success in multicandidate, multiparty election campaigns remains unproven. Not only are there relatively few studies of campaign spending effects in multiparty systems, there are none examining the effect under the Single Transferable Vote (STV) electoral system. Our study ex...

Given a functor T : C → D carrying a class of morphisms S ⊂ C into a class S ⊂ D, we give sufficient conditions in order that T induces an equivalence on the localised categories. These conditions are in the spirit of Quillen’s theorem A. We give some applications in algebaic and birational geometry. Introduction Let T : C → D be a functor and S ⊂ C, S ⊂ D two classes of morphisms containing id...

There are many double complexes in the mathematics and physics literature which are related to BRST transformations and anomalies, e.g. Variational-, BRST-, Faddeev-, Koszul-Tate-, Weil-, GelfandFuks-, semi infinite-, Cech-DeRham-, foliation-, Lie group/algebrabicomplex. The goal is to identify them and to establish relations between them; to compute their cohomologies and the corresponding ano...

Consider a set A of binary sequences, or equivalently, a subset of Cantor set. Players I and II play binary bits alternatively for infinitely many turns, forming an infinite binary sequence; player I wins if the sequence is in A, and, otherwise, player II wins. We say that A is determined if one of the players has a winning strategy for this game. Statements about determinacy of games have attr...

A large two-body scattering length leads to universal behavior in few-body systems. In particular, the three-body system displays interesting features such as exact discrete scale invariance in the bound state spectrum in the limit of infinite scattering length. Here, I will discuss how an effective field theory (EFT) can be used to study these features and how the finite range of the underlyin...

Very significant advances have been made in the relativistic theory of few body systems since I visited Peter Sauer and his group in Hannover in 1983. This talk provides an opportunity to review the progress in this field since then. Different methods for the realtivistic calculation of few nucleon systems are briefly described. As an example, seven relativistic calculations of the deuteron ela...

Bismuth telluride (Bi2Te3) and related compounds have recently attracted strong interest, owing to the discovery of the topological insulator properties in many members of this family of materials. The few-quintuple films of these materials are particularly interesting from the physics point of view. We report results of the micro-Raman spectroscopy study of the “graphene-like” exfoliated few-q...
