Abstract
We discuss the conditions under which the BRST operator of a W-string can be written as the sum of two operators that are separately nilpote nt and anticommute with each other. We illustrate our results with the example of the non-critical W3-string. Furthermore, we apply our resu lts to make a conjecture about a relationship between the spectrum of a non-critical W(n)-string and a W(n-1)-string.
