A method for determining the generalised scaling function(s) which arises in the large spin behaviour of the long operator anomalous dimension in the planar sl(2) sector of N = 4 SYM is proposed. The all-orders perturbative expansion at strong coupling for the third and the fourth generalised scaling functions is worked out, finding perfect agreement with today’s results from the O(6) NonLinear...

We show that every Hilbert C∗-module E is a JB∗-triple in a canonical way and establish an explicit expression for the holomorphic automorphisms of the unit ball of E. 1.

As a sequel of [4], this paper is devoted to the computation of the digital fundamental group πd 1(O/S;σ) defined by loops in the digital object O for which the digital object S acts as an “obstacle”. We prove that for arbitrary digital spaces the group πd 1(O/S;σ) maps onto the usual fundamental group of the difference of continuous analogues |AO∪S | − |AS |. Moreover, we show that this epimor...

A study of the convergence properties of spectral projected subgradient method is presented and the convergence is shown. The convergence is based on spectral projected gradient approach. Some updates of the spectral projected subgradient are described.
