SUMMARY:Computability Theory Learning Seminar
CLASS:PUBLIC
DESCRIPTION:JOEY LAKERDAS-GAYLE\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSI
 TY OF\nWATERLOO\n\n\"DEGREE SPECTRA OF COMPUTABLE STRUCTURES - PART I\"\n\
 nThe isomorphism spectrum of a pair of isomorphic computable structures\ni
 s the set of Turing degrees that compute an isomorphism between the\nstruc
 tures. The categoricity spectrum of a computable structure is the\nset of 
 Turing degrees that compute an isomorphism between every pair\nof computab
 le copies of the structure. We will investigate some\nproperties of these 
 spectra and give some examples.\n\nMC 5403
