Retraction of the complement of smooth projective hypersurfaces to an $n$-dimensional $\Delta$-complex

E. Artal, A. Larraya Sancho, M. A. Marco Buzunariz

We give an explicit strong deformation retraction of the complement of a Fermat hypersurface of degree $d$ in the complex projective space of dimension $n$ into a $\Delta$-complex of re…
