Query: Quantum 3D Tensionless String in Light-cone Gauge   We discuss the quantization of a tensionless closed string in light-cone
gauge. It is known that by using a Hamiltonian BRST scheme the tensionless
p-branes have no Lorentz anomaly in any space-time dimensions and no anomaly of
space-time conformal symmetry in two dimensions. In this paper, we show that
tensionless 3d strings in light-cone gauge also have no anomaly of space-time
conformal symmetry. We also study the spectrum of a tensionless 3d closed
string.
