Emergence on sandpile models

Thời gian: 09:30 đến 11:30 Ngày 26/05/2016

Tóm tắt:
The talk will be twofold:

1. A presentation of the great two-dimensional sandpiles folklore. This
includes playing with a simulator, algebraic properties, and beautiful
images.

2. Our contribution to the field: we formally prove the emergence of
very regular shapes on one-dimensional sandpile configurations, without
requiring a perfect understanding of the dynamics (joint work with Eric
Rémila). This includes some linear algebra and combinatorics.
