Dear all,
    this is to announce the next SISSA/IGAP algebraic geometry seminar.

SPEAKER:    Michele Graffeo - SISSA

TITLE:         Crepant resolutions of symplectic quotient singularities
as  moduli spaces of constellations.

WHEN:        Thursday, April 22 at 4.30pm (Rome)

WHERE:      Link Zoom:

                  ID riunione:          862 9233 3052
                  Passcode:             327926

ABSTRACT: It is a well known fact that, given a finite subgroup G <
SL(n,C) (n=2,3) there exists a crepant resolution of the singularity 
C^n/G which parametrizes "scheme theoretic orbits of the G action". In
the seminar I will start by explaining the above sentence and then I
will show how G-constellations help to fit the above statement ina  more
general context.
The key words of this seminar are:
1. Group theory
2. Resolution of singularities & birational transformations
3. Combinatorics
4. Commutative algebra
5. Stability conditions (following King)
6. Many many examples. 

Best regards,
Andrea, Alessandro and Michele
