DESCRIPTION:Speaker: Ashleigh Adams (North Dakota State University)\n\nTitl
 e: Webification of symmetry classes of plane partitions\n\nAbstract: Plane
  partitions are a combinatorial objects generalizing Young diagrams. They 
 have beautiful combinatorial properties\, such as product counting formula
 s for their symmetry classes. Recently\, plane partitions have been shown 
 by Gaetz\, Pechenik\, Pfannerer\, Striker\, and Swanson to be in bijection
  with certain U_q(sl_4)-webs lying on a hexagonal grid. These webs can be 
 viewed as combinatorial objects called hourglass plabic graphs and have de
 ep representation theoretic connections to quantum invariant theory. In th
 is talk\, I will discuss the connection between these seemingly unrelated 
 combinatorial objects. Moreover\, I will give a classification of the symm
 etry classes of plane partitions via lattice words obtained from analyzing
  trip permutations of the corresponding hourglass plabic graphs and give a
  combinatorial map between certain nice U_q(sl_4)-webs and U_q(sl_2)-webs\
 , as well as give some representation theoretic implications.
