On the Number of Components of the Symplectic Representatives of the Canonical Class
Stefano Vidussi
In this paper we show that there exists a family of simply connected, symplectic 4-manifolds such that the (Poincare dual of the) canonical class admits both connected and disconne…
Nontrivial Alexander polynomials of knots and links
Stefan Friedl, Stefano Vidussi
In this paper we present a sequence of link invariants, defined from twisted Alexander polynomials, and discuss their effectiveness in distinguish knots. In particular, we recast a…
Twisted Alexander polynomials and symplectic structures
Stefan Friedl, Stefano Vidussi
Let N be a closed, oriented 3-manifold. A folklore conjecture states that S^1 x N admits a symplectic structure only if N admits a fibration over the circle. The purpose of this pa…
Homologous Non-isotopic Symplectic Surfaces of Higher Genus
B. Doug Park, Mainak Poddar, Stefano Vidussi
We construct an infinite family of homologous, non-isotopic, symplectic surfaces of any genus greater than one in a certain class of closed, simply connected, symplectic four-manif…
