On 2d TQFTs whose values are holomorphic symplectic varieties
Gregory W. Moore, Yuji Tachikawa
For simple and simply-connected complex algebraic group G, we conjecture the existence of a functor eta_G from the category of 2-bordisms to the category of holomorphic symplectic…

Instanton counting with a surface operator and the chain-saw quiver
Hiroaki Kanno, Yuji Tachikawa
We describe the moduli space of SU(N) instantons in the presence of a general surface operator of type N=n_1+ ... +n_M in terms of the representations of the so-called chain-saw qu…

On W-algebras and the symmetries of defects of 6d N=(2,0) theory
Yuji Tachikawa
We consider 6d N=(2,0) theory on N M5-branes, together with a 4d defect labeled by a Young diagram Y specifying its global symmetry G_Y. A recent conjecture states that a compactif…
