Embedding questions for Weinstein and contact manifolds.
Amey Kaloti, University of Arkansas
[Abstract] [PDF]
Abstract: We describe a framework for embedding Weinstein 4-manifolds into Weinstein 6-manifolds using Lefschetz fibrations. The process also reframes the "spun embeddings" of Etnyre and Lekili used to describe embeddings of contact 3-manifolds into contact 5-manifolds. We'll discuss obstructions as well as examples including Weinstein 6-manifolds which contain all Weinstein 4-manifolds as properly embedded Weinstein submanifolds. Joint work with Jeremy Van Horn-Morris.
