Some Algebro-Geometric Aspects of The SL(2, R) Wess-Zumino-Witten Model of Strings on an ADS Background
Bogdan G. Dimitrov
The SL(2, R) WZW model of strings on an ADS3 background is investigated in the spirit of J.Maldacena's and H.Ooguri's approach (hep-th/0001053) and (hep-th/0005183). Choosing a sta…

Flows and particles with shear-free and expansion-free velocities in (L^-_n,g)- and Weyl's spaces
Sawa Manoff, Bogdan Dimitrov
Conditions for the existence of flows with non-null shear-free and expansion-free velocities in spaces with affine connections and metrics are found. On their basis, generalized We…
