Earlier Hermite showed the equival ence of Galois groups with geometric monodromy groups\, and in 1979 Harris initiated the modern study of Galois groups of enumerative problems. He p osited that a Galois group should be ‘as large as possible’ in that it will be the largest group preserving internal symmetry in the geometric p roblem.\n\nI will describe this background and discuss some work in a long -term project to compute\, study\, and use Galois groups of geometric prob lems\, including those that arise in applications of algebraic geometry. A main focus is to understand Galois groups in the Schubert calculus\, a we ll-understood class of geometric problems that has long served as a labora tory for testing new ideas in enumerative geometry.\n LOCATION:https://researchseminars.org/talk/NASO/19/ END:VEVENT END:VCALENDAR
