On the one loop equivalence of dual σ models
It is shown that in the one loop order of perturbation theory the coupling constant and parameter(s) of an (Abelian T) dual sigma model get renormalized in the same way as in the ‘original’ model.

The Nappi-Witten string in the light-cone gauge
Some of the motivations for as well as the main points of the quantization of the Nappi-Witten string in the light-cone gauge are reviewed.

On a problem of spontaneous compactification
We investigate how the equations governing spontaneous compactification to nonsymmetric coset spaces can be solved for two particular classes of internal spaces.

Spontaneous compactification to non-symmetric spaces
We investigate the spontaneous compactification of 4+d dimensions toM 4 ×K/H whereK/H is ad-dimensional non-symmetric space. We present a formula giving the complete massless spinor spectrum for allK/H spaces. We...

On the local commutativity of quantized scalar and vector fields
The connection between the locality of the interpolating and asymptotic fields is studied in case of scalar and vector particles.
