Abstract:

We construct the BRST operator for non-critical

W_3

-strings and discuss the tachyon-like spectrum. For

N

-punctured spheres with

N \leq 5

we briefly describe a formal definition of the integral over

W_3

-moduli space.

string model: W(3)
operator: Becchi-Rouet-Stora
gravitation
moduli space
operator: tachyon
