Holomorphic Chern-Simons theories and twisted holography

Twisted holography was introduced by Costello, Li and Gaiotto as duality between twisted subsectors of bulk/boundary theories. They are mathematically formalized as Koszul duality between bulk/boundary algebra of local observables. In this talk I will review on recent progress of the holomorphic Chern-Simons theories in 4d and 5d, as examples of twisted holography. There is a conjectured 6d version of this series of dualities, which will be outlined at the end of this talk.
