Dear all,

*Vis. Asst.Prof. Dr. Nur Sağlam*  from Virginia Polytechnic Institute and
State University will give a talk titled    *“ *Geography Problem of
Symplectic 4-Manifolds  "  on June 11th at 14:00. All interested are
invited.

Abstract: The world of 4-manifolds is very interesting in many senses. For
example, a closed topological n-manifold Xn has exactly one smooth
structure if n ≤ 3 and has at most finitely many smooth structures if n >
4. However, there are many simply-connected closed 4-manifolds which admit
infinitely many smooth structures. Also, classification problems for
smooth, simply connected 4-manifolds have still not fully been understood.
For example, the generalized Poincaré conjecture is still open for
dimension 4. In this talk, we will talk about the construction of
symplectic 4-manifolds homeomorphic but not diffeomorphic to some
well-known manifolds with given topological invariants. We will mostly focus
on the simply-connected symplectic 4-manifolds, describe the topological
invariants, and give examples.

Microsoft Teams platform will be used for the seminar. To join the seminar,
