DEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملString–string Triality for D = 4, Z 2 Orbifolds †
We investigate the perturbative and non-perturbative correspondence of a class of four dimensional dual string constructions with N = 4 and N = 2 supersymmetry, obtained as Z2 or Z2 × Z2 orbifolds of the type II, heterotic and type I string. In particular, we discuss the heterotic and type I dual of all the symmetric Z2 × Z2 orbifolds of the type II string, classified in Ref. [1]. † Research su...

متن کاملFour-dimensional black holes in string theory.
Exact solutions of heterotic string theory corresponding to fourdimensional charge Q magnetic black holes are constructed as tensor products of an SU(2)/Z(2Q+2) WZW orbifold with a (0, 1) supersymmetric SU(1, 1)/U(1) WZW coset model. The spectrum is analyzed in some detail. “Bad” marginal operators are found which are argued to deform these theories to asymptotically flat black holes. Surprisin...
متن کامل-non-perturbative Four-Dimensional String Cosmology
Starting from an exact (in the Regge slope α ′ ) functional method for a bosonic stringy σ-model, we investigate four-dimensional cosmological string solutions in graviton, dilaton and antisymmetric tensor backgrounds, compatible with world-sheet conformal invariance, and valid beyond perturbative expansions in powers of α ′ . The antisymmetric tensor field, playing the rôle of an axion in the ...
