Spin structures on complex projective spaces and circle actions
Donghoon Jang
It is known that the complex projective space admits a spin structure if and only if is odd. In this paper, we provide another proof that doe…
Circle actions on 6-dimensional oriented manifolds with 4 fixed points
Donghoon Jang
In this paper, we classify the fixed point data (weights and signs at the fixed points), of a circle action on a 6-dimensional compact oriented manifold with 4 fixed points. We pro…
Almost complex torus manifolds -- graphs, Hirzebruch genera, and problem of Petrie type
Donghoon Jang
Let a -dimensional torus act on a -dimensional compact connected almost complex manifold with isolated fixed points. As for circle actions, we show that there exis…
Graphs for torus actions on oriented manifolds with isolated fixed points and classification in dimension 6
Donghoon Jang
Let a torus act on a compact oriented manifold with isolated fixed points, with an additional mild assumption that its isotropy submanifolds are orientable. We associate a sign…
