Abstract

We describe the Stein handlebody diagrams of Milnor fibers of Brieskorn singularities xp+yq+zr=0x^p + y^q + z^r = 0. We also study the natural symplectic operation by exchanging two Stein fillings of the canonical contact structure on the links in the case p=q=rp = q = r, where one of the fillings comes from the minimal resolution and the other is the Milnor fiber. We give two different interpretations of this operation, one as a symplectic sum and the other as a monodromy substitution in a Lefschetz fibration.
