## Abstract We consider a string stretched between two diagonal branes on a bosonic torus under a perturbation of one of the radii. In the world‐sheet description, this corresponds to a perturbation of a conformal field theory with two boundary components. A term in the second order boundary RG equ

This paper addresses the problem on how to evaluate various operators used for estimation of derivatives in images. Such operators are extremely commonly used, for instance to detect edges. For bandlimited correctly sampled signals ideal derivative operators are easy to define. For 2D signals the fi

## Abstract It is shown that the determination of a unique scaling parameter, based on scale‐invariant forms for energy in the scaled zero‐order Hamiltonian approach of Feenberg, is not possible because the higher‐order invariants themselves are nonunique.
