> Abstract:  In this talk, I will introduce a surgery operation referred to
> as
> 'twist-rim surgery' to change embeddings of surfaces in 4-manifolds. This
> surgery is a modification of the rim surgery introduced by Fintushel-Stern
> and provides 'exotic' knotted surfaces in a 4-manifold: surfaces whose
> embeddings are homeomorphic but not diffeomorphic.  Twist-rim surgery has
> been applied to knotting algebraic curves in CP^2 and led to solve the
> problem 4.110 in the classic Kirby Problem List, namely finding surfaces
> in CP^2 that are homologous to smooth algebraic curves (called degree
> d-curve),but are not smoothly  isotopic to them.
