I have just started taking a look at some introductory papers about Shimura varieties, after a friend of mine suggested me to do so. They seem to be a sort of very interesting and many-sided topic, but the approach I am following is the algebraic geometric one, as he studies algebraic geometry. Since I am not an algebraic geometer, I was wondering whether there exist some more topological aspects of those complex objects, perhaps even related with hyperbolic geometry, topology or so. I know that Shimura varieties are mainly used by number theorists and algebraic geometers, but I'd like to know about approaches different from those.

I know it kinda appears as a very vague, imprecise question, but it would be nice to know these facts in advance, so that I'll be able to keep studying from the more 'appropriate' (for me, of course) point of view.

Thank you, bye

Hi, can you tell us which reference you are following? I am also interested in studying these beasts... :) – expmat Jan 12 '12 at 18:19
Yes, sure: I'm reading "Introduction to Shimura Varieties" by J.S. Milne. You can freely download it from the website of the author. Have fun! – Damiano Lupi Jan 12 '12 at 19:04
Btw, I just remembered a professor once recommended the following paper: "The notion of a Shimura variety" by Kumar Murty. I haven't read it yet though... – expmat Jan 12 '12 at 19:14
Then the first few chapters are indeed "topological" (Riemannian metric, curvature, locally symmetric space...), and he probably gives references there, too. – shenghao Jan 13 '12 at 2:12
unfortunately I am afraid he does not give any topological reference still related with Shimura Varieties... – Damiano Lupi Jan 17 '12 at 11:44
