Inanc Baykur (UMass) Title: Small symplectic and exotic 4manifolds via positive factorizations Abstract: We will discuss new ideas and
techniques for producing positive Dehn
twist factorizations of surface mapping
classes (joint work with Mustafa Korkmaz)
which yield novel constructions of
interesting symplectic and smooth
4manifolds, such as small symplectic
CalabiYau surfaces and exotic rational
surfaces, via Lefschetz fibrations and
pencils. Peter Feller (Boston College) Eugene Gorsky (UC Davis) Mark Hughes (BYU) A question of Rudolph asks to describe a
method for determining whether a given
braid or link is quasipositive. Orevkov
presented a method for answering this
question in the case of 3strand braids.
In this talk we present an algorithm for
detecting quasipositive braids of any
index. These techniques make use of
mapping class orderings of Rourke and
Wiest. The question of detecting quasipositive
links is much harder, and remains open. We
will however discuss computational methods
which in many cases can aid in the
recognition of quasipositive links. Xin Jin (Northwestern)
