An exotic 5RP^2 in the 4-sphere

Gordana MatiÄ, Ferit ÃztÃ¼rk, Javier Reyes +2

We show an example of an embedded copy of 5RP^2 in the four-sphere which is topologically standard but smoothly knotted, i.e. smoothly not isotopic to the standard embedding.

Smooth structures on four-manifolds with finite cyclic fundamental groups

R. Inanc Baykur, Andras I. Stipsicz, Zoltan Szabo

For each nonnegative integer m we show that any closed, oriented topological four-manifold with fundamental group Z_{4m+2} and odd intersection form, with possibly seven exceptions…

A note on surfaces in $CP^{2}$ and $CP^{2} # CP^{2}$

Marco Marengon, Allison N. Miller, Arunima Ray +1

In this brief note, we investigate the $CP^{2}$ -genus of knots, i.e. the least genus of a smooth, compact, orientable surface in $CP^{2} ∖ B^{4} ˚$ boun…
