Different features of interaction among harmonic research and approximation conception are lined during this quantity. the subjects integrated are Fourier research, functionality areas, optimization conception, partial differential equations, and their hyperlinks to fashionable advancements within the approximation thought. The articles of this assortment have been originated from occasions. the 1st occasion happened through the 9^{th} ISAAC Congress in Krakow, Poland, 5th-9th August 2013, on the part “Approximation conception and Fourier Analysis”. the second one occasion was once the convention on Fourier research and Approximation thought within the Centre de Recerca Matem`tica (CRM), Barcelona, in the course of 4th-8th November 2013, equipped through the editors of this quantity. All articles chosen to be a part of this assortment have been rigorously reviewed.

**Particle swarm optimisation : classical and quantum optimisation**

Even supposing the particle swarm optimisation (PSO) set of rules calls for really few parameters and is computationally uncomplicated and simple to enforce, it's not a globally convergent set of rules. In Particle Swarm Optimisation: Classical and Quantum views, the authors introduce their proposal of quantum-behaved debris encouraged through quantum mechanics, which results in the quantum-behaved particle swarm optimisation (QPSO) set of rules.

Bm is a regular mapping. By definition, a holomorphic mapping ' W Bn ! Bm /; a very close notion was earlier introduced in the Bloch-to-BMOA setting (see [3]). In fact, we show that the scheme applied in [6] is adaptable to the logarithmic Bloch spaces. The main result of the present paper is the following theorem. 2 Let ˛ < 12 , 0 < p Ä 1 and let ' W Bn !
