Description of the Attainable Sets of One-Dimensional Differential Inclusions
The role played by the attainable set of a differential inclusion, in the study of dynamic control systems and fuzzy differential equations, is widely acknowledged. A procedure for estimating the attainable set is rather complicated compared to the numerical methods for differential equations. This article addresses an alternative approach, based on an optimal control tool, to obtain a descript...
متن کاملGenerating Sets of Completely 0-simple Semigroups
A formula for the rank of an arbitrary finite completely 0-simple semigroup, represented as a Rees matrix semigroup M[G; I,Λ;P ] , is given. The result generalises that of Ruškuc concerning the rank of connected finite completely 0-simple semigroups. The rank is expressed in terms of |I| , |Λ| , the number of connected components k of P and a number rmin which we define. We go on to show that t...
متن کاملCharacterizing Intraregular Semigroups by Intuitionistic Fuzzy Sets
In this paper, we give some theorems which characterizes the intraregular semigroups in terms of intuitionistic fuzzy left, right, and biideals.
متن کاملBipolar Valued Fuzzy Sets in Γ-Semigroups
In this paper the notions of bipolar valued fuzzy subsemigroup, bipolar valued fuzzy bi-ideal, bipolar valued fuzzy (1,2)ideal and bipolar valued fuzzy ideal in a Γ-semigroup have been introduced. Some important characterizations are also obtained. Mathematics Subject Classification: 20M12, 03F55, 03E72
متن کاملOptimal Low-Thrust, Invariant Manifold Trajectories via Attainable Sets
A method to incorporate low-thrust propulsion into the invariant manifolds technique is presented in this paper. The low-thrust propulsion is introduced by means of special attainable sets that are used in conjunction with invariant manifolds to define a first guess solution. This is later optimized in a more refined model where an optimal control formalism is used. Planar low-energy, low-thrus...
