ds. The computation is based on a tessellation of the worldsheet into inte
grable hexagon patches\, and it naturally includes a discretization of the
string theory moduli space. The weak-coupling expansion is extremely effi

ansatz equations (BAE). In particular\, I will present new methods to coun
t the number of physical solutions with fixed quantum numbers based on Gr
öbner basis and quotient ring. This method can be applied to study the co
mpleteness of Bethe ansatz. I will then discuss an efficient analytical me
thod to compute the sum of on-shell physical quantities over all physical
solutions without explicitly solving BAE. We apply this method to compute
and study torus partition functions of the 6-vertex model at finite size.
Finally\, we find new internal structure of solution space of BAE and give
the physical interpretations.\n\nhttps://indico.nbi.ku.dk/event/1050/cont

DESCRIPTION:Speakers: Balázs Pozsgay ()\nIn a CFT with a defect the sca
ling operators can have non vanishing mean values. At one loop order in pl
anar N=4 SYM the normalization constants of these one-point functions are
given by the overlaps between the corresponding Bethe states and a particu
lar Matrix Product State (MPS). These MPS are not eigenstates of the spin
chain\, but they display very special features: the overlaps are non-zero
only for parity symmetric Bethe root configurations\, and can be expressed
in a factorized form. In this talk we focus on the algebraic properties o
f these MPS: we explain their relation to boundary integrability and the t
wisted Yangian\, and show how they can be obtained from the twisted Bounda
ry Yang-Baxter relation.\n\nhttps://indico.nbi.ku.dk/event/1050/contributi

DESCRIPTION:Speakers: Leonardo Rastelli ()\nAny ${\\cal N}=2$ $4d$ superco

al algebra\, or vertex operator algebra (VOA). The VOA computes a rich cl
ass of observables of the SCFT. In the opposite direction\, four-dimension
al physics expectations lead to interesting mathematical conjectures for V
OAs. Most ambitiously\, one hopes to use this $4d/2d$ correspondence as on
organizing principle for the whole landscape of ${\\cal N}=2$ SCFTs. In
this talk\, I will review the basics of the correspondence and describe so
me 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 ene
rgy effective field theory on the Higgs branch of the $4d$ theory.\n\nhttp

DESCRIPTION:Speakers: Elli Pomoni ()\nIn this talk we will explain how to
obtain the instanton partition functions of a large class of N=1 superconf

s via orbifolding. We can study the Coulomb branch of these theories by co
nstructing and analyzing their spectral curves. Employing our experience w
ith the AGT correspondence we will search for a 2D/4D relation for the N=1
SCFTs\nin class Sk. From the curves we can identify the 2D CFT symmetry a
lgebra and its representations\, namely the conformal blocks of the \nVira
soro/W-algebra\, that underlie the 2D theory and reproduce the spectral cu
rves of the N = 1 SCFTs. These conformal blocks give a prediction for the
instanton partition functions of the 4D N = 1 SCFTs\nof class Sk. Finally\
, we will present a completely independent\, elliptic genus calculation\,
counting open string states on Dp/D(p-4) brane systems in type IIB string
theory\, which exactly reproduces our\nprevious result for the instanton p

DESCRIPTION:Speakers: Amit Sever ()\nAt higher orders in the 1/N expansion
\, scattering amplitudes receives contributions from diagrams of higher ge
nus. We view these higher genus contributions as gluing of planar objects
in momentum space. This is done by identifying the spacetime momentum that
flows around the cycles of the 't Hooft surface. We focus on the first no
n-planar correction to gluon scattering amplitudes in N=4 SYM theory. The
correction takes the form of a double trace partial amplitude and the corr
esponding 't Hooft surface has the topology of a cylinder. It is suppresse
d by one power of 1/N with respect to the leading single trace contributio
n. We extend the duality between planar scattering amplitudes and null pol
ygonal Wilson loops to the double trace amplitude. The new duality relates
the amplitude at any fixed momentum flow around the cylinder to the corre
lation function of two infinite null polygonal Wilson lines that are subje
ct to a quantum periodicity constraint. We test the duality perturbatively
at one-loop order and demonstrate it for the dual string in AdS. The dual
ity allows us to extend the notion of the loop integrand beyond the planar
limit and to determine it using recursion relations. It also allows us to
apply the integrability-based pentagon operator product expansion approac
h to the first non-planar order.\n\nhttps://indico.nbi.ku.dk/event/1050/co

DESCRIPTION:Speakers: Benjamin Basso ()\nI will discuss the thermodynamica
l limit of planar diagrams in the 4d fishnet theory\, an integrable matrix
scalar theory which stands as a close relative of the N=4 Super-Yang-Mill
s theory. Using integrable techniques developed for studying the scaling d
imensions of single trace operators in N=4 SYM\, I will argue that the con
tinuum limit of the fishnet diagrams is governed by the 2d AdS5 non-linear
sigma model.\n\nhttps://indico.nbi.ku.dk/event/1050/contributions/7608/
