RIMS & OIST Workshop: On the Problem of Resolution of Singularities and its Vicinity

  • Date: Monday, June 10 - Friday June 14, 2019
  • Venue:  Seaside house, Okinawa Institute of Science and Techonology Graduate University

The goal of this workshop is to study the recent developments on one of the most long-standing and fundamental problems in Algebraic Geometry, the problem of resolution of singularities in positive characteristic, and communicate the results in its surrounding areas, with a view toward its ultimate solution. The workshop will give us a unique opportunity for the world leaders on the problem and the active experts on the subject to gather at one place and carry out intensive discussions in a seminar-style environment. We also aim at disseminating the basic techniques and methods among the younger researchers and students through the lectures given in the morning
