Surface observables in gauge theories, modular Painlevé tau functions and non-perturbative topological strings
Giulio Bonelli, Pavlo Gavrylenko, Ideal Majtara +1
We study BPS surface observables of four dimensional gauge theory in gravitational -background at perturbative and at Argyres-Douglas superconformal fixe…
On the boundary gauge dual of closed tensionless free strings in AdS
G. Bonelli
We consider closed free tensionless strings in , calculate exactly the boundary/boundary string evolution kernel and find the string dynamics to be completely frozen. We int…
On the covariant quantization of tensionless bosonic strings in AdS spacetime
G. Bonelli
The covariant quantization of the tensionless free bosonic (open and closed) strings in AdS spaces is obtained. This is done by representing the AdS space as an hyperboloid in a fl…
Matrix String Models for Exact (2,2) String Theories in R-R Backgrounds
G. Bonelli
We formulate matrix string models on a class of exact string backgrounds with non constant RR-flux parameterized by a holomorphic prepotential function and with manifest (2,2) supe…
Matrix Strings in pp-wave backgrounds from deformed Super Yang-Mills Theory
G. Bonelli
We formulate matrix models for strings in ten dimensional pp-wave backgrounds and for particles in eleven dimensional ones. This is done by first characterizing the deformations of…
Counting BPS states of the M-5brane
G. Bonelli
An on-shell model for the supersymmetric index counting multiplicities of BPS states of the M5-brane theory is reviewed. In particular we explicitly study the tensionless Little St…
The M5-brane on K3 and del Pezzo's and multi-loop string amplitudes
G. Bonelli
We study the BPS spectrum of Little String Theory for bound states of M5-branes wrapped on six manifold of product topology and the apparence of multi-loop -funct…
Six Dimensional Topological Gravity and the Cosmological Constant Problem
G. Bonelli, A. M. Boyarsky
We formulate a topological theory in six dimensions with gauge group SO(3,3) which reduces to gravity on a four dimensional defect if suitable boundary conditions are chosen. In su…
Holography and CFT on Generic Manifolds
G. Bonelli
In this paper it is shown how the AdS/CFT correspondence extends to a more general situation in which the first theory is defined on (d+1)-dimensional manifold defined a…
RG Flow Irreversibility, C-Theorem and Topological Nature of 4D N=2 SYM
G. Bonelli, M. Matone
We determine the exact beta function and a RG flow Lyapunov function for N=2 SYM with gauge group SU(n). It turns out that the classical discriminants of the Seiberg-Witten curves…
Nonperturbative Relations in N=2 SUSY Yang-Mills and WDVV equation
G. Bonelli, M. Matone
We find the nonperturbative relation between , the prepotential and the vevs in su…
Nonperturbative Renormalization Group Equation and Beta Function in N=2 SUSY Yang-Mills
G. Bonelli, M. Matone
We obtain the exact beta function for SUSY Yang-Mills theory and prove the nonperturbative Renormalization Group Equation $$ \partial_Λ{\cal F}(a,Λ)= {Λ\over Λ_0}\par…
Algebraic-geometrical formulation of two-dimensional quantum gravity
G. Bonelli, P. A. Marchetti, M. Matone
We find a volume form on moduli space of double punctured Riemann surfaces whose integral satisfies the Painlevé I recursion relations of the genus expansion of the specific heat o…
Nonperturbative 2D Gravity, Punctured Spheres and -Vacua in String Theories
G. Bonelli, P. A. Marchetti, M. Matone
We consider a model of 2D gravity with the coefficient of the Einstein-Hilbert action having an imaginary part . This is equivalent to introduce a -vacuum structure in the…
