Non-Negativity
is a Quantum Phenomenon
Oberwolfach
1--7 March 2009
In recent publications, the same
combinatorial description has arisen for three separate objects of
interest: non-negative cells in the real grassmannian (Postnikov,
Williams); torus orbits of symplectic leaves in the classical
grassmannian (Brown, Goodearl and Yakimov); and, torus invariant prime
ideals in the quantum grassmannian (Launois, Lenagan and Rigal). The
aim of this meeting is to explore the reasons for this coincidence in
the grassmannian in particular, and to explore similar ideas in more
general settings.
