The interplay between the algebraic, differential, and topological natures of a variety is largely governed by the structure of cycles on the variety. Moduli spaces play a central role in modern geometry and the study of their cycle structures is an incredibly rich subject that has seen major advances in recent years. The aim of this conference is to bring together researchers studying cycles on moduli spaces from various perspectives.
The conference will focus on recent contributions to the study of both their algebraic and topological cycle structures with techniques arising from enumerative geometry, Hodge theory, derived categories, and representation theory.

L’interaction entre les aspects algébriques, différentielles et topologiques d’une variété est largement régie par la structure des cycles sur la variété. Les espaces de modules jouent un rôle central dans la géométrie moderne et l’étude de leurs structures de cycle est un sujet incroyablement riche qui a connu des avancées majeures ces dernières années.
L’objectif de cette conférence est de rassembler des chercheurs étudiant les cycles sur les espaces de modules sous diverses perspectives. La conférence se concentrera sur les contributions récentes à l’étude de leurs structures de cycles algébriques et topologiques avec des techniques issues de la géométrie énumérative, de la théorie de Hodge, des catégories dérivées et de la théorie des représentations.
