SUMMARY:Number Theory Seminar
CLASS:PUBLIC
DESCRIPTION:EMILY QUESADA-HERRERA\, UNIVERSITY OF LETHBRIDGE\n\nFourier opt
 imization and the least quadratic non-residue\n\nWe will explore how a Fou
 rier optimization framework may be used to\nstudy two classical problems i
 n number theory involving Dirichlet\ncharacters: The problem of estimating
  the least character non-residue\;\nand the problem of estimating the leas
 t prime in an arithmetic\nprogression. In particular\, we show how this Fo
 urier framework leads\nto subtle\, but conceptually interesting\, improvem
 ents on the best\ncurrent asymptotic bounds under the Generalized Riemann 
 Hypothesis\,\ngiven by Lamzouri\, Li\, and Soundararajan. Based on joint w
 ork with\nEmanuel Carneiro\, Micah Milinovich\, and Antonio Ramos.\n\nMC 5
