On the heat equation and index theorem

WebIn this paper, we give a new proof of the localization formulas of Berline and Vergne [9] and Duistermaat and Heckman [18]. When interpreted in the framework of Atiyah [2], the probabilistic heat equation proof of the Index Theorem given in our paper [12] appears as the rigorous infinite dimensional version of this new proof of the localization formulas in … WebReviews.

From a variational perspective, we study the convergence analysis of expansive and almost-expansive curves and sequences governed by an evolution equation of the monotone or non-monotone type. Finally, we propose two well …
