 Exotic 4-Manifold Constructions via Pencils of Curves of Small  Genus and 
 Surgeries</a>\nby Sumeyra Sakalli (Max Planck Institute for Mathematics) a
 s part of Bilkent Topology Seminar\n\nLecture held in SB-Z11.\n\nAbstract\
 nExotic manifolds are smooth manifolds which are homeomorphic but not\ndif
 feomorphic to each other. Constructing exotic manifolds in dimension\nfour
  has been an active research area in low dimensional and symplectic\ntopol
 ogy over the last 30 years. In this talk\, we will first discuss major\nop
 en problems and some recent progress in 4-manifolds theory. Then we\nwill 
 discuss our constructions of exotic 4-manifolds via pencils of complex\ncu
 rves of small genus and via symplectic and smooth surgeries. Some of\nour 
 results that will be presented are joint with A. Akhmedov.\n
