Hi, everyone: I apologize if this is out of place. Please let me know if so, and feel free to remove. I am trying to get into the world of 4-manifolds. I was wondering how to get someone to help me get started. I have taken classes in diff. geom. and hyperbolic geometry, and my analysis , topology, functional analysis are pretty good (all grad-PHD level). I understand the topic is vast and complex-- therefore the need for advisement. I am hoping towork more on the analytic side (i.e, diff. manifolds) , maybe "Functional-Analytic" than the purely topological one, tho I understand there will be heavy topological aspects nonetheless. Could someone please suggest how to get advisement? (my school is not exactly what you'd call the nurturing or supportive type, and my request for help there was largely ignored, tho I was told--at least so I understood-- that if I could do the work on my own, that I could go on and work in the area.). I understand the topic is complex and very open-ended, so that I do not expect short -term results. I am also still pretty motivated to put in 8+ hours/day 7 days /week. (I finally found a good energy drink to help me with it:) ) Thanks for your suggestions.
