SUMMARY:Computability Theory Learning Seminar
CLASS:PUBLIC
DESCRIPTION:LUKE MACLEAN\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSITY OF W
 ATERLOO\n\n\"BACK-AND-FORTH RELATIONS OF ABELIAN GROUPS\"\n\nWe will provi
 de a partial characterization of the back-and-forth\nrelations on countabl
 e reduced Abelian p-groups. This will\, in turn\,\nhelp us to provide uppe
 r bounds on the Scott complexities of such\nstructures. This work relies h
 eavily on Ulm's theorem\, and so a proof\nsketch will be given.\n\nMC 5403
