On Thermodynamical Properties of Some Coset CFT Backgrounds
A. Giveon, A. Konechny, E. Rabinovici +1
We investigate the thermodynamical features of two Lorentzian signature backgrounds that arise in string theory as exact CFTs and possess more than two disconnected asymptotic regi…

Strings in Singular Time-Dependent Backgrounds
Amit Giveon, Eliezer Rabinovici, Amit Sever
We review the construction of time-dependent backgrounds with space-like singularities. We mainly consider exact CFT backgrounds. The algebraic and geometric aspects of these backg…
