DESCRIPTION:Title: <a href="https://researchseminars.org/talk/viasmag/1/">
 Mac Lane valuations and an application to resolution of quotient singulari
 ties</a>\nby Andrew Obus as part of VIASM Arithmetic Geometry Online Semin
 ar\n\n\nAbstract\nMac Lane's technique of "inductive valuations" is over 8
 0 years old\, but has only recently been used to attack problems about ari
 thmetic surfaces. We will give an explicit\, hands-on introduction to the 
 theory\, requiring little background beyond the definition of a non-archim
 edean valuation. \n\nWe will then outline how this theory is helpful for r
 esolving "weak wild" quotient singularities of arithmetic surfaces\, a cla
 ss of singularity studied by Lorenzini that shows up naturally when comput
 ing models of curves with potentially good reduction.\n\n<a href="https://
