Abstract

We study little string theory on R1 x S5, defined by a theory which lives on type IIA N NS5 branes wrapped on S5, using its supergravity dual. In particular we study semiclassical rotating closed strings in this background. We also consider Penrose limit of this background that leads to a plane wave on which string theory is exactly solvable.
