A note on Todorov surfaces
Let S be a Todorov surface, i.e., a minimal smooth surface of general type with q = 0 and pg = 1 having an involution i such that S/i is birational to a K3 surface and such that the bicanonical map of S is composed with i. The main result of this paper is that, if P is the minimal smooth model of S/i, then P is the minimal desingularization of a double cover of P ramified over two cubics. Furth...
متن کاملTransseries and Todorov-Vernaeve's asymptotic fields
We study the relationship between fields of transseries and residue fields of convex subrings of non-standard extensions of the real numbers. This was motivated by a question of Todorov and Vernaeve, answered in this paper. In this note we answer a question by Todorov and Vernaeve (see, e.g., [35]) concerning the relationship between the field of logarithmic-exponential series from [14] and the...
متن کاملAn algebraic proof of Bogomolov-Tian-Todorov theorem
We give a completely algebraic proof of the Bogomolov-Tian-Todorov theorem. More precisely, we shall prove that if X is a smooth projective variety with trivial canonical bundle defined over an algebraically closed field of characteristic 0, then the L∞-algebra governing infinitesimal deformations of X is quasi-isomorphic to an abelian differential graded Lie algebra.
متن کاملAlexander Todorov A Statistical Model of Facial Attractiveness
Previous research has identified facial averageness and sexual dimorphism as important factors in facial attractiveness. The averageness and sexual dimorphism accounts provide important first steps in understanding what makes faces attractive, and should be valued for their parsimony. However, we show that they explain relatively little of the variance in facial attractiveness, particularly for...
متن کامل¿Curar el cáncer? Los orígenes de la radioterapia española en el primer tercio del siglo XX
ethical choices-but it raises challenges that have not been fully solved. The result creates an asymmetry. The earlier chapters include accounts of how each of the four main scientists discussed responded to National Socialism and fared under the Nazi stateWertheimer and Goldstein were prominent members of the intellectual migration. The last chapter, however, attempts to examine "wholeness" as...
