SUMMARY:Math Seminar Series
DESCRIPTION:
 Combinatorics and Graph Theory\n
 \n
 Anna Weigandt 
 from University of Michigan will be speaking.\n
 \n
 The 
 presentation is titled "Transition 
 on Grothendieck Polynomials."\n
 \n
 This is a virtual 
 meeting that takes place via Zoom.\n
 \n
 The 
 description of the event is as follows:\n
 Using 
 anti-diagonal Gröbner geometry, Knutson 
 and Miller explained how Grothendieck polynomials 
 arise as K-polynomials of matrix Schubert 
 varieties. We will discuss how Lascoux's transition 
 equations for Grothendieck polynomials 
 can be realized geometrically through "almost 
 anti-diagonal" Gröbner degeneration of matrix 
 Schubert varieties. In particular, under 
 this strange term order, Fulton's generators 
 form a Gröbner basis. Our proof involves studying 
 the lattice of alternating sign matrices.\n\n
