Off-shell string physics
Robert C. Myers, Vipul Periwal
Recent advances in non-critical string theory allow a unique continuation, preserving conformal invariance, of critical Polyakov string amplitudes to off-shell momenta. These conti…
Conformally invariant off-shell string physics
Robert C. Myers, Vipul Periwal
Using recent advances in the understanding of non-critical strings, we construct a unique, conformally invariant continuation to off-shell momenta of Polyakov amplitudes in critica…
Quantizing Effective Strings
J. D. Cohn, Vipul Periwal
This TASI lecture covers the material in hep-th/9205026. It reviewed the theory of effective strings, with particular emphasis on the manner in which Lorentz invariance is represen…
Chiral Non-Critical Strings
R. C. Myers, V. Periwal
It is shown that conformal matter with $c_{\ssc L}\not=c_{\ssc R}$ can be consistently coupled to two-dimensional `frame' gravity. The theory is quantized in conformal gauge, follo…
Chiral gravity in two dimensions
R. C. Myers, V. Periwal
It is shown that conformal matter with $c_{\ssc L}\not=c_{\ssc R}$ can be consistently coupled to two-dimensional `frame' gravity. The theory is quantized, following David, and Dis…
Non-analyticity in the large N renormalization group
Vipul Periwal
The flow of the action induced by changing is computed in large matrix models. It is shown that the change in the action is non-analytic. This non-analyticity appears at th…
