Improved actions for the two-dimensional σ-model
In recent years there has been much work in improving lattice actions (see e.g. M. Lüscher’s and P. Hasenfratz’ talks at this conference). The idea behind all these attempts is to modify the lattice action with the addition of irrelevant operators in order to reduce lattice artifacts: the aim is to have scaling and finite-size-scaling at small values of the correlation length. Two different app...
متن کاملThe Geometry of two dimensional Supersymmetric Nonlinear σ Model
In this report, we investigate the relation between supersymmetry (twisted and untwisted) and geometry for two dimensional σ model with target spaces of arbitrary signature, and Lorentzian or Euclidean world sheets. It can be shown that the number of allowed supersymmetry is constrained purely by the geometric considerations. The possible geometries are classified according to properties of the...
متن کامل3-dimensional topological σ-model ∗
A 3-dimensional model dual to the Rozansky-Witten topological sigma-model with a hyper-Kähler target space is considered. It is demonstrated that a Feynman diagram calculation of the classical part of its partition function yields the Milnor linking number.
متن کامل-loop Improved Lattice Action for the Nonlinear Σ-model *
In this paper we show the Wilson effective action for the 2-dimensional O(N + 1)-symmetric lattice non-linear σ-model computed in the 1-loop approximation for the nonlinear choice of blockspin Φ(x), Φ(x) = Cφ(x)/|Cφ(x)|,where C is averaging of the fundamental field φ(z) over a square x of sideã. The result for S ef f is composed of the classical perfect action with a renormalized coupling const...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
