SUMMARY:Big numbers, small factors, and Shimura varieties.
DESCRIPTION:Speaker: Tonghai Yang\, University of Wisconsin, Madison\n\nIt was observed 90 years ago that the famous modular j -function has the following cool property j ( 1 + - 1 6 3 2 ) = - e 1 6 3 π + 7 4 4 + t i n y = - 2 1 8 3 3 5 3 2 3 3 2 9 3 --> is a huge integer with very small prime factor, and so is j ((1+√-163)/2)-1728. In the early 80s, Gross and Zagier …
