Isogenous to a Product of Curves
A smooth algebraic surface S is isogenous to a product, not of mixed type, if there exist two smooth curves C, F and a finite group G, acting faithfully on both C and F and freely on their product, so that S = (C × F )/G. In this paper we classify the surfaces of general type with pg = q = 1 which are isogenous to an unmixed product, assuming that the group G is abelian. It turns out that they ...
متن کاملON SURFACES OF GENERAL TYPE WITH pg = q = 1 ISOGENOUS TO A PRODUCT OF CURVES
A smooth algebraic surface S is said to be isogenous to a product of unmixed type if there exist two smooth curves C, F and a finite group G, acting faithfully on both C and F and freely on their product, so that S = (C × F )/G. In this paper we classify the surfaces of general type with pg = q = 1 which are isogenous to an unmixed product, assuming that the group G is abelian. It turns out tha...

متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولOn standardized models of isogenous elliptic curves
Let E, E′ be isogenous elliptic curves over Q given by standardized Weierstrass models. We show that (in the obvious notation) a1 = a1, a ′ 2 = a2, a ′ 3 = a3 and, moreover, that there are integers t, w such that a4 = a4 − 5t and a6 = a6 − b2t − 7w, where b2 = a1 + 4a2.
