SUMMARY:Number Theory Seminar
CLASS:PUBLIC
DESCRIPTION:KEIRA GUNN (UNIVERSITY OF CALGARY)\n\nSome Problems on the Dyna
 mics of Positive Characteristic Tori.\n\nThe real (or characteristic zero)
  torus is simply R/Z\, or the \"decimal\npart\" of any real number with op
 erations of addition and integer\nmultiplication.  With the positive char
 acteristic integers defined to\nbe polynomials with coefficients from a fi
 nite field\, and the positive\ncharacteristic reals their Laurent series c
 ounterparts\, we can\nsimilarly construct the positive characteristic tori
  (each torus\ndependent on the choice of field).  At first glance there a
 re many\nsimilarities to how operations work in both positive and zero\nch
 aracteristic\, but these similarities break down quickly upon further\nins
 pection\, particularly from a view of dynamics on the tori.\n\nIn this tal
 k\, we will discuss results on some orbital sets and\ndynamics formulae on
  the positive characteristic tori\, including the\nArtin-Mazur zeta functi
 on and analogous hypothesis for Furstenberg's\nOrbital Theorem.\n\nMC5403
