VBAC 2026 Conference - Vector Bundles on Algebraic Curves

VBAC 2026 Conference

VBAC 2026: Curves, Surfaces and Moduli

Universidad Autónoma de Yucatán (UADY), Mérida, Yucatán, Mexico, 19-23 January, 2026

In honour of Leticia Brambila-Paz

The VBAC committee has decided to focus the 2026 conference on the following themes: bundles and their generalisations including on higher dimensional varieties, Brill-Noether theory, tropical geometry, as well as the geometry of moduli spaces. These are very active topics of research which interact with many areas of geometry and promise to generate a lot of new activity and progress in the future. In recognition of former VBAC chair Leticia Brambila-Paz’s many contributions to mathematics, both scientific and fostering its development in Mexico and beyond, we have found it very appropriate to dedicate this meeting to her, in her home country.
