Holomorphic quantum field theories (HQFT) are defined on complex manifolds, with all the invariants, such as correlation functions, being holomorphic (i.e., annihilated by the ∂-derivatives). They are higher-dimensional analogs of chiral conformal field theories in two real (one complex) dimensions. Just as topological eld theories (where the correlators are annihilated by all derivatives) play a fundamental role in the topology of smooth manifolds, HQFTs are of great importance in complex algebraic geometry. For instance, anomalies in such theories are related to the Grothendieck-Riemann-Roch theorem for complex manifolds. An early example of a HQFT was the Kodaira-Spencer (KS) gravity theory of Bershadsky-Cecotti-Ooguri-Vafa. Other examples include the holomorphic Chern-Simons theory as well as various holomorphic twists of supersymmetric eld theories. Recent years have seen remarkable developments in HQFT. New insights from factorization algebras and derived geometry open up a purely algebraic theory of higher-dimensional analogs of vertex algebras and classical infinite-dimensional Lie algebras (such as Kac-Moody and Virasoro algebras). The understanding of the KS gravity and of its relations with the holomorphic Chern-Simons was greatly advanced by recent work of Costello-Li, and more recently has lead to a twisted holography proposal by Costello-Gaiotto.

The conference will bring together theoretical physicists and mathematicians working in algebraic geometry, derived geometry and factorization algebras.
