A canonical connection on bundles on Riemann surfaces and Quillen connection on the theta bundle

چکیده

We investigate the symplectic geometric and also differential aspects of moduli space connections on a compact connected Riemann surface X . Fix theta characteristic K 1 / 2 ; it defines divisor M stable vector bundles rank r degree zero. Given bundle E ? lying outside divisor, we construct natural holomorphic connection that depends holomorphically Using this connection, canonical isomorphism between following two: (1) C pairs ( , D ) where is (2) Conn ? given by sheaf line associated to divisor. The above structure preserving, moves as runs over family surfaces.

Singular connection and Riemann theta function

We prove the Chern-Weil formula for SU(n + 1)-singular connections over the complement of an embedded oriented surface in smooth four manifolds. The expression of the representation of a number as a sum of nonvanishing squares is given in terms of the representations of a number as a sum of squares. Using the number theory result, we study the irreducible SU(n+ 1)-representations of the fundame...

1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...

Line Bundles on Super Riemann Surfaces

We give the elements of a theory of line bundles, their classification, and their connec-tions on super Riemann surfaces. There are several salient departures from the classicalcase. For example, the dimension of the Picard group is not constant, and there is nonatural hermitian form on Pic. Furthermore, the bundles with vanishing Chern numberaren’t necessarily flat, nor can every such bundle b...
