Evaluation of Euler Number of Complex Grassmann Manifold G(k, N) via Mathai-Quillen Formalism
Shoichiro Imanishi, Masao Jinzenji, Ken Kuwata
In this paper, we provide a recipe for computing Euler number of Grassmann manifold G(k,N) by using Mathai-Quillen formalism (MQ formalism) and Atiyah-Jeffrey construction. Especia…

Holomorphic Vector Field and Topological Sigma Model on CP^1 World Sheet
Masao Jinzenji, Ken Kuwata
Witten suggested that fixed-point theorems can be derived by the supersymmetric sigma model on a Riemann manifold M with potential term induced from Killing vector on M. One of the…
