Conformal Field Theory and Torsion Elements of the Bloch Group
Werner Nahm
We argue that rational conformally invariant quantum field theories in two dimensions are closely related to torsion elements of the algebraic K-theory group K_3(C). If such a theo…
A generalization of Le Potier's vanishing theorem
F. Laytimi, W. Nahm
We prove a new vanishing theorem generalizing that of Le Potier for Schur functors of a vector bundle.
The associative algebras of conformal field theory
David Brungs, Werner Nahm
Modulo the ideal generated by the derivative fields, the normal ordered product of holomorphic fields in two-dimensional conformal field theory yields a commutative and associative…
Vanishing theorems for products of exterior and symmetric powers
F. Laytimi, W. Nahm
For ample vector bundles over compact complex varieties and a Schur functor corresponding to an arbitrary partition of the integer , one would like to know t…
On the Seiberg-Witten Approach to electric-magnetic Duality
Werner Nahm
Electric-magnetic duality allows to calculate the central charges of N=2 supersymmetric theories with massless hypermultiplets as derivatives of simple modular forms. The procedure…
