Our main theorem is an extension of this result to semigroups of algebraic operators on a Banach space. We also obtain a related theorem for a pair [A, B] of arbi

We prove uniqueness of "invariant measures," i.e., solutions to the equation L \* Β΅ = 0 where L = βˆ† + B β€’ βˆ‡ on R n with B satisfying some mild integrability conditions and Β΅ being a probability measure on R n . This solves an open problem posed by S. R. S. Varadhan in 1980. The same conditions are s
