Wall theorems

In differential topology in mathematics, the Wall theorems are four results, which connect the smooth structure, auto-diffeomorphisms and the intersection form of a smooth 4-manifold with h-cobordisms, stable diffeomorphisms and induced form automorphisms. The theorems are named after C. T. C. Wall, who proved them in 1964.
