In this note, we study necessary and sufficient conditions for the existence of a Spin-dimensional cobordism that supports a non-singular and non-degenerate pseudo-Riemannian metric of signature, which restricts to a non-singular time-orientable Lorentzian metric on its boundary. The corresponding cobordism groups are computed.

Abstract
In this note, we study necessary and sufficient conditions for the existence of a Spin-dimensional cobordism that supports a non-singular and non-degenerate pseudo-Riemannian metric of signature, which restricts to a non-singular time-orientable Lorentzian metric on its boundary. The corresponding cobordism groups are computed.File in questo prodotto:
