The computation is based on a tessellation of the worldsheet into integra

ring theory moduli space. The weak-coupling expansion is extremely efficie
nt in the large-charge limit. Finite charges require a careful treatment o

to compute the sum of on-shell physical quantities over all physical solu

study torus partition functions of the 6-vertex model at finite size. Fina

Matrix Product State (MPS). These MPS are not eigenstates of the spin cha

y for parity symmetric Bethe root configurations\, and can be expressed in
a factorized form. In this talk we focus on the algebraic properties of t

algebra\, or vertex operator algebra (VOA). The VOA computes a rich class
of observables of the SCFT. In the opposite direction\, four-dimensional
physics expectations lead to interesting mathematical conjectures for VOAs
. Most ambitiously\, one hopes to use this $4d/2d$ correspondence as on or
ganizing principle for the whole landscape of ${\\cal N}=2$ SCFTs. In thi
s talk\, I will review the basics of the correspondence and describe some
recent progress in characterizing the class of VOAs that descend from $4d$
SCFTs. The new insight is the VOA is intimately related to the low energy
effective field theory on the Higgs branch of the $4d$ theory.\nhttps://i

DESCRIPTION:Speakers: Amit Sever\nAt higher orders in the 1/N expansion\,
scattering amplitudes receives contributions from diagrams of higher genus
. We view these higher genus contributions as gluing of planar objects in
momentum space. This is done by identifying the spacetime momentum that fl
ows around the cycles of the 't Hooft surface. We focus on the first non-p
lanar correction to gluon scattering amplitudes in N=4 SYM theory. The cor
rection takes the form of a double trace partial amplitude and the corresp
onding 't Hooft surface has the topology of a cylinder. It is suppressed b
y one power of 1/N with respect to the leading single trace contribution.
We extend the duality between planar scattering amplitudes and null polygo
nal Wilson loops to the double trace amplitude. The new duality relates th
e amplitude at any fixed momentum flow around the cylinder to the correlat
ion function of two infinite null polygonal Wilson lines that are subject
to a quantum periodicity constraint. We test the duality perturbatively at
one-loop order and demonstrate it for the dual string in AdS. The duality
allows us to extend the notion of the loop integrand beyond the planar li
mit and to determine it using recursion relations. It also allows us to ap
ply the integrability-based pentagon operator product expansion approach t
o the first non-planar order.\nhttps://indico.nbi.ku.dk/event/1050/contrib
