Non-time-orientable lorentzian cobordism allows for pair creation

Abstract

It is shown that if time-orientability is sacrificed, then, in any spacetime of odd dimension, two cobordant manifolds are also related by a Lorentzian cobordism. Thus, pair creation of Kaluza-Klein monopoleswould be allowed in such a framework. The even-dimensional case is also examined.
