We prove the BMV (Bessis, Moussa, Villani, 1975) conjecture, which states that the function t -> Tr exp(A-tB), t ≥ 0, is the Laplace transform of a positive measure on [0,∞) if A and B are n x n Hermitian matrices and B is positive semidefinite. A semi-explicit representation for this measure is given.
