Global magniicence, or: 4G Networks

Nikita Nekrasov, Nicolo Piazzalunga

The global magnificent four theory is the homological version of a maximally supersymmetric -dimensional gauge theory on a Calabi-Yau fourfold fibered over a circle. In the…

Interfaces and Quantum Algebras, I: Stable Envelopes

Mykola Dedushenko, Nikita Nekrasov

The stable envelopes of Okounkov et al. realize some representations of quantum algebras associated to quivers, using geometry. We relate these geometric considerations to quantum…

Novikov-Veselov Symmetries of the Two-Dimensional Sigma Model

Igor Krichever, Nikita Nekrasov

We show that Novikov-Veselov hierarchy provides a complete family of commuting symmetries of two-dimensional sigma model. In the first part of the paper we use these symmetr…

Intersecting defects in gauge theory, quantum spin chains, and Knizhnik-Zamolodchikov equations

Saebyeok Jeong, Norton Lee, Nikita Nekrasov

We propose an interesting BPS/CFT correspondence playground: the correlation function of two intersecting half-BPS surface defects in four-dimensional supersymmetri…

Surface defects in gauge theory and KZ equation

Nikita Nekrasov, Alexander Tsymbaliuk

We study the regular surface defect in the Omega-deformed four-dimensional supersymmetric gauge theory with gauge group SU(N) with 2N hypermultiplets in fundamental representation.…

Playing with the index of M-theory

Michele Del Zotto, Nikita Nekrasov, Nicolo' Piazzalunga +1

Motivated by M-theory, we study rank n K-theoretic Donaldson-Thomas theory on a toric threefold X. In the presence of compact four-cycles, we discuss how to include the contributio…
