SUMMARY:Number Theory Seminar
CLASS:PUBLIC
DESCRIPTION:Summary \n\nPAUL POLLACK\, UNIVERSITY OF GEORGIA\n\nHow nonuniq
 ue is your factorization?\n\nNumber theorists learn early on not to take u
 nique factorization for\ngranted. In 1980\, R.J. Valenza introduced the \"
 elasticity” of an\nintegral domain as a means of measuring how far away 
 the domain is\nfrom possessing unique factorization. I will survey what is
  known\nabout elasticity of rings of number theoretic interest. Particular
 \nattention will be paid to recent work of the speaker on elasticity of\no
 rders in quadratic fields. Much of this is joint with Steve Fan (UGA)\nand
  Enrique Trevino (Lake Forest).\n\nMC 5417\n
