Abstract
Let WA be the vector field Lie algebra with values in the Frobneius algebra A of rank N. We show that the second continuous cohomology group is H2(WA,K)=â¨k=1NKÏk,K=âorA,where Ï1,â¦,ÏN are â-valued basic Gelfand-Fuchs cocycles. As an application, we present a generalized Virasoro algebra virA[α1,â¦,αk]. We also consider another kind of generalization and propose a multi-component Frobenius-Virasoro algebra virA[n] and study its related Euler-type equations.
