Representability of Aut F and End F 1 Statement of Results
Recently N. Nitsure showed that for a coherent sheaf F on a noetherian scheme the automorphism functor AutF is representable if and only if F is locally free. Here we remove the noetherian hypothesis and show that the same result holds for the endomorphism functor EndF even if one asks for representability by an algebraic space.
متن کاملThe polarization of F 1 strings into D 2 branes : “ Aut Caesar aut nihil 1 ”
We give matrix and supergravity descriptions of type IIA F-strings polarizing into cylindrical D2 branes. When a RR four-form field strength F4 is turned on in a supersymmetric fashion (with 4 supercharges) , a complete analysis of the solutions reveals the existence of a moduli space of F1 → D2 polarizations (Caesar) for some fractional strengths of the perturbation, and of no polarization wha...
متن کاملf-DERIVATIONS AND (f; g)-DERIVATIONS OF MV -ALGEBRAS
Recently, the algebraic theory of MV -algebras is intensively studied. In this paper, we extend the concept of derivation of $MV$-algebras and we give someillustrative examples. Moreover, as a generalization of derivations of $MV$ -algebraswe introduce the notion of $f$-derivations and $(f; g)$-derivations of $MV$-algebras.Also, we investigate some properties of them.
متن کاملOn End and Coupled Endpoints of $theta$-$F$-Contractive Set-Valued Mappings
In this paper, we introduce a new concept in set-valued mappings which we have called condition $(UHS)$. Then, adding this condition to a new type of contractive set-valued mappings, recently has been introduced by Amini-Harandi [Fixed and coupled fixed points of a new type contractive set-valued mapping in complete metric spaces, Fixed point theory and applications, 215 (2012)], we prove that ...
