Generalizations of the Sugawara Model
نویسندگان
چکیده
Two generalizations of Sugawara models are discussed. En the first, new interactions are introduced by altering the current commutators but retaining the "free" form of T„„,as exemplified by a simple effective x -2y interaction, which is compared with the standard triangle-diagram results. The second permits nonquadratic T„„,which retain the "algebra" part of the current commutators; these models avoid the DashenFrishman parity degeneracy.

A Mathematical Optimization Model for Solving Minimum Ordering Problem with Constraint Analysis and some Generalizations
In this paper, a mathematical method is proposed to formulate a generalized ordering problem. This model is formed as a linear optimization model in which some variables are binary. The constraints of the problem have been analyzed with the emphasis on the assessment of their importance in the formulation. On the one hand, these constraints enforce conditions on an arbitrary subgraph and then g...
متن کاملAn Optimization Model for Epidemic Mitigation and Some Theoretical and Applied Generalizations
In this paper, we present a binary-linear optimization model to prevent the spread of an infectious disease in a community. The model is based on the remotion of some connections in a contact network in order to separate infected nodes from the others. By using this model we nd an exact optimal solution and determine not only the minimum number of deleted links but also their exact positions. T...
متن کاملGeneralizations of Borel-Cantelli Lemma
The Borel-Cantelli Lemma is very important in the probability theory. In this paper, we first describe the general case of the Borel-Cantelli Lemma. The first part of this lemma, assuming convergence and the second part includes divergence and independence assumptions. In the following, we have brought generalizations of the first and second part of this lemma. In most generalizat...
متن کاملOrdered Weighted Averaging Operators and their Generalizations with Applications in Decision Making
The definition of ordered weighted averaging (OWA) operators and their applications in decision making are reviewed. Also, some generalizations of OWA operators are studied and then, the notion of 2-symmetric OWA operators is introduced. These generalizations are illustrated by some examples.
متن کاملGeneralizations of the Skew t-Normal Distribution and their Properties
In this paper we consider several generalizations of the skew t-normal distribution, and some of their properties. Also, we represent several theorems for constructing each generalized skew t-normal distribution. Next, we illustrate the application of the proposed distribution studying the ratio of two heavy metals, Nickel and Vanadium, associated with crude oil in Shadgan wetland in the south-...
