The method of round handle decomposition of manifolds was introduced by D. Asimov in 1970's, in order to study the non-singular Morse-Smale flows. In some sense, it seems the method is suitable to the study of contact manifolds. I introduced a new construction method of contact manifolds, that is, contact round surgery.

In this talk, I will give the definition of symplectic round handles
and contact round surgeries. In addition, I will talk on some properties obtained from this method.
