Quantum Non-linear Sigma-Models
自然辩证法This is the first comprehensive presentation of the quantum non-linear sigma-models. The original papers consider in detail geometrical properties and renormalization of a generic non-linear sigma-model, illustrated by explicit multi-loop calculations in perturbation theory. 978364208689200266Starting from this dematerialization hypothesis, for the first time comparative case-studies analyse in detail the driving forces of industrial restructuring of different industries and countries in Europe where such a decline has been ob
