We present exact expressions for certain integrated correlators of four superconformal primary operators in the stress tensor multiplet of $\cN=4$ supersymmetric Yang--Mills (SYM) theory with classical gauge group, $G_N$ $= SO(2N)$, $SO(2N+1)$, $USp(2N)$.

The perturbation theory for linear operators of discrete type [PDF]
A perturbation result for unbounded operators of discrete type [\textit{N. Dunford} and \textit{J. Schwartz}, Linear Operators, part III (1971; Zbl 0243.47001): Spectral Operators, XIX, 2, Theorem 7] is derived using the notion of unconditional basis instead of assuming weak completeness of the underlying Banach space.

Quark-Antiquark Effective Potential in Symplectic Quantum Mechanics
In this paper, we study within the structure of Symplectic Quantum Mechanics a bidimensional nonrelativistic strong interaction system which represent the bound state of heavy quark-antiquark, where we consider a Cornell potential which consists of ...

Yang-Mills form factors on self-dual backgrounds
The construction of perturbative quantities on non-linear backgrounds leads to the possibility of incorporating strong field effects in perturbation theory.

A complete non-perturbative renormalization prescription for quasi-PDFs
In this work we present, for the first time, the non-perturbative renormalization for the unpolarized, helicity and transversity quasi-PDFs, in an RI′ scheme.

Asymptotic Integration of Certain Differential Equations in Banach Space
We investigate the problem of constructing the asymptotics for weak solutions of certain class of linear differential equations in the Banach space as the independent variable tends to infinity.

Integrating by parts at finite density
Both nonzero temperature and chemical potentials break the Lorentz symmetry present in vacuum quantum field theory by singling out the rest frame of the heat bath.

Finite-dimensional perturbations of linear operators and some applications to boundary integral equations [PDF]
Finite-dimensional perturbing operators are constructed using some incomplete information about eigen-solutions of an original and/or adjoint generalized Fredholm operator equation (with zero index).

PERTURBATION THEORY FOR ELECTROMAGNETIC WAVE SCATTERING IN RANDOM LAYERED STRUCTURES [PDF]
The problem of electromagnetic wave scattering in 3-D random layered structures, is analytical treated by relying on original results of the Boundary Perturbation Theory (BPT) and Volumetric-Perturbative Reciprocal Theory (VPRT), whose structured ...
