We study discrete Green’s functions and their relationship with discrete Laplace equations. Several methods for deriving Green’s functions are discussed. Green’s functions can be used to deal with diffusion-type problems on graphs, such as chip-firing, load balancing and discrete Markov chains.

2014 Interatomic Green functions are computed here for transition metals using a real space technique, namely the recursion method The results for the case of the FCC structure are compared to those derived from band structure calculations using a k-space technique, namely the tetrahedron method. We show here that the agreement between both calculations is as good as for usual intra-atomic Gree...

The PROMETHEE is a significant method for evaluating alternatives with respect to criteria in multi-criteria decision-making problems. It is characterized by many types of preference functions that are used for assigning the differences between alternatives in judgements. This paper proposes a preference of green suppliers using the PROMETHEE under the usual criterion preference functions. Comp...

Spin-dependent electronic transport through two coupled single-level quantum dots attached to ferromagnetic leads with parallel and antiparallel magnetizations is analyzed theoretically. The intra-dot Coulomb correlation is taken into account, while the inter-dot Coulomb repulsion is omitted. Conductance and tunnel magnetoresistance associated with magnetization rotation are calculated by the n...

the purpose of this study is identification and barrier analysis for green supply chain management implementation in sirjan's golgohar using fuzzy topsis technique and fuzzy dematel technique. at first, in this study barriers for green supply chain management are identified through literature and survey with experts and the priority processing is doing with fuzzy topsis technique. this study is...

Green functions associated to complex reflection groups G(e, 1, n) were discussed in the author’s previous paper. In this paper, we consider the case of complex reflection groups W = G(e, p, n). Schur functions and Hall-Littlewood functions associated to W are introduced, and Green functions are described as the transition matrix between those two symmetric functions. Furthermore, it is shown t...

this study aimed to investigate the factors affecting intention of citizens toward participating in activities related to development and protection of green spaces in tehran. the research was descriptive-correlation and survey method was used. the statistical population of this study consisted of all citizens in tehran. using proportional and stratified random sampling, 626 citizens were selec...
