Abstract
Let be a projective algebraic -variety endowed with isolated determinantal singularities, and let be a -form on exhibiting a finite number of singularities (in the stratified sense). Under some technical conditions, we use two generalizations of Poincar\'e-Hopf index with the goal of proving a Poincar\'e-Hopf Type Theorem for .
