bstract\nThe purpose of our lectures is to give a short but self-contained
overview of some well-known results about the geometry of algebraic group
actions. We will focus mainly on the actions of connected reductive group
s. Our main goals are 1) introducing some interesting examples of equivari
ant completions of homogeneous spaces\, 2) explaining several combinatoria
l gadgets such as valuation cones\, weight monoids\, colors\, etc. that ar
e not only useful for classifying algebraic actions of low complexity but
also essential for understanding these equivariant completions. Along the
way\, we will review some representation theory. In addition\, we will ana
lyze some concrete examples of combinatorial varieties such as toric and S
chubert varieties.\n\nZoom Meeting ID 974 3685 2246\n\nPassword Initials o

DESCRIPTION:Title: Lecture 1: The Delzant construction\nby Joé Brendel (Uni
versity of Neuchâtel) as part of GGTI Online Seminars\n\n\nAbstract\nTori
c symplectic manifolds are symplectic manifolds with an effective Hamilton
ian torus action of maximal dimension. Toric manifolds are distinguished b
y the property that they can be reconstructed from a combinatorial object
called the moment polytope. Thus they are a great playground for symplecti
c topology and the study of Lagrangian submanifolds\, since complicated in
variants may be reduced to combinatorial properties of the corresponding m
oment polytope. In recent years\, there has been much interest in a genera
lization called “almost toric” structures.\n\nIn these four lectures\,
we will introduce these two classes of symplectic manifolds\, and use the
ir special structure to study Lagrangian tori and symplectic embedding pro
blems.\n\nPlease find the Zoom ID/password from the seminar homepage:\n\nh
