Moduli spaces of spacefilling branes in symplectic 4-manifolds, by M. Zambon
29 Jan 2026, 14:00 CET. Talk by Marco Zambon. Abstract: On a symplectic manifold (M, ω), a spacefilling brane structure is a closed 2-form F which determines a complex structure, with respect to which F + iω is holomorphic symplectic. For holomorphic symplectic compact Kähler 4-manifolds, we show that the moduli space of spacefilling branes…

Gugenheim’s A-infinity de Rham theorem and higher holonomies, by C. Arias-Abad
—
in 2025/202617 Dec 2025, 14:00 CET. Talk by Camilo Arias-Abad. Abstract: The de-Rham map, that takes a differential form to a singular cochain by integration over chains, is not an algebra map. It should not be, since differential forms are commutative but singular cochains are not. However, the map induced in cohomology is an algebra map.…

A brief introduction to deformation quantization, by H. Bursztyn
—
in 2025/202611 Dec 2025, 15:00 CET. Talk by Henrique Bursztyn. Abstract: This (informal) talk will introduce and discuss some aspects of deformation quantization, including its motivation, basic examples, and existence and classification of star products. Time permitting, I will also comment on the connections with “B-fields” and Morita equivalence.
