SUMMARY:Pure Math Grad Colloquium
CLASS:PUBLIC
DESCRIPTION:XINGCHI RUAN\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSITY OF W
 ATERLOO\n\n\"LOWER BOUNDS ON SOLUBILITY OF DIOPHANTINE SYSTEMS\"\n\nGiven 
 a system of r homogeneous polynomial equations with degree d\nwith rationa
 l coefficients\, we study the number of variables it needs\nto possess a n
 on-trivial p-adic solution. We focus on the lower bound\nof this number. W
 e learn the history and prototype of the problem\, as\nwell as the most pr
 ecise estimation of the lower bound so far.\n\nMC 5479
