Семинар на Ernesto Lupercio

На 12.03.2026 г. (четвъртък), от 13:15 ч. в зала 300 на ИЯИЯЕ, Prof. Ernesto Lupercio (CINCESTAV and IMI-BAS) ще изнесе доклад на тема:

"Residues as Renormalized Couplings in Self-Organized Criticality"

Резюме: I present a QFT-style renormalization framework for SOC sandpile dynamics: a tropical spectrum of caustic events defines a zeta function whose residues are scheme-independent observables. The distinguished residue at (s=2/3) recovers equiaffine curvature (affine arclength), while the dense-forcing limit yields a Monge–Ampère effective field.
