The study of the h-cobordism theorem and 2-spheres in 4-manifolds

Abstract

In this paper, we would like to investigate the h-cobordism Theorem and the Poincare' Conjecture, Also we would like to find a Counter example of the Whitney's Lemma in dimension 4.;본 논문에서는 h-cobordism 이론과 Poincare의 Cojecture를 연구해 보고자 한다. 또한 본 논문에서는 Whitney의 보조정리에 위배되는 예를 4차원상에서 찾고자한다.
