Kawakubo and Uchida showed that, if a closed oriented 4k-dimensional manifold M admits a semi-free circle action such that the dimension of the fixed point set is less than 2k,then the signature of M ...
This paper contains several results concerning circle action on almost-complexand smooth manifolds. More precisely, we show that, for an almost-complex manifoldM2mn(resp. a smooth manifold N4mn), if t...
