SUMMARY:Spin^h and further generalisations of spin
CLASS:PUBLIC
DESCRIPTION:MICHAEL ALBANESE\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSITY 
 OF\nWATERLOO\n\nThe question of which manifolds are spin or spin^c has a s
 imple and\ncomplete answer. In this talk we address the same question for 
 the\nlesser known spin^h manifolds which have appeared in geometry and\nph
 ysics in recent decades. We determine the first obstruction to being\nspin
 ^h and use this to provide an example of an orientable manifold\nwhich is 
 not spin^h. The existence of such an example leads us to\nconsider an infi
 nite sequence of generalised spin structures. In doing\nso\, we determine 
 an answer to the following question: is there an\ninteger k such that ever
 y manifold embeds in a spin manifold with\ncodimension at most k?\n\nThis 
 is joint work with Aleksandar Milivojevic.\n\nMC 5417
