Thom–Sebastiani Theorem
text:
In complex analysis, a branch of mathematics, the Thom–Sebastiani Theorem states: given the germ f : → defined as f = f 1 + f 2 where f i are germs of holomorphic functions with isolated singularities, the vanishing cycle complex of f is isomorphic to the tensor product of those of f 1 , f 2 . Moreover, the isomorphism respects the monodromy operators in the sense: T f 1 ⊗ T f 2 = T f . The theorem was introduced by Thom and Sebastiani in 1971. Observing that the analog fails in positive charact
