Abstract: We utilize the Ozsvath-Szabo contact invariant to detect the
action of involutions on certain homology spheres that are surgeries on
symmetric links, generalizing a previous result of Akbulut and Durusoy.
Potentially this may be useful to detect different smooth structures on
$4$-manifolds by cork twisting operation. This is a joint work with S.
Akbulut.
