Most traditional neuropsychological work concerns aspects of cognition in the most ordinary sense: how the average person perceives and represents the world, and how she acts in response to what is perceived or felt. The extraordinary perception and action of artists has been a subject of fascination for some neuropsychologists at least since Alajouanine, but little systematic work has been don...

alexander sergeyevich griboyedov was a russian diplomat, playwright, and composer. he is recognized in russian literature as a dramatist and writer of a book, whose fame rests on the brilliant verse comedy woe from wit (the woes of wit), a satire on russian aristocratic society which continus to be one of the most often staged plays in russia. however, in iran he is known as the great russian a...

9 An acyclic coloring is a proper coloring with the additional property that the union of 10 any two color classes induces a forest. We show that every graph with maximum degree at 11 most 5 has an acyclic 7-coloring. We also show that every graph with maximum degree at 12 most r has an acyclic (1 + b (r+1) 2 4 c)-coloring. 13

Möbius number systems represent points using sequences of Möbius transformations. Thorough the paper, we are mainly interested in representing the unit circle (which is equivalent to representing R ∪ {∞}). The main aim of the paper is to improve already known tools for proving that a given subshift–iterative system pair is in fact a Möbius number system. We also study the existence problem: How...

We prove that for every k and every ε > 0, there exists g such that every graph with tree-width at most k and odd-girth at least g has circular chromatic number at most 2 + ε.

Alexandr Kostochka In search of ways to attack Hadwiger’s Conjecture, Woodall and independently Seymour suggested to prove the weaker conjecture that Every (s + t)-chromatic graph has a Ks,t-minor. If the conjecture were true for all values of s and t, it would imply that for k ≥ 2 every (2k − 2)-chromatic graph has a Kk-minor. The conjecture is evident for s = 1. The validity of the conjecture...

This paper extends Alexandr Chayanov's model of changing household demography (specifically the ratio of food consumers to food producers) and its influence on agricultural behavior so that it includes possible adverse effects of a rising ratio on nutritional status and early childhood mortality within the household. We apply the model to 35 years' worth of longitudinal demographic and economic...

In Batalin-Vilkovisky formalism a classical mechanical system is specified by means of a solution to the classical master equation. Geometrically such a solution can be considered as a QP -manifold, i.e. a supermanifold equipped with an odd vector field Q obeying {Q,Q} = 0 and with Q-invariant odd symplectic structure. We study geometry of QP manifolds. In particular, we describe some construct...
