http://ijim.srbiau.ac.ir/article_10488_1731.html
In this paper, we study the separtion axioms $T_0,T_1,T_2$ and $T_{5/2}$ on topological and semitopological residuated lattices and we show that they are equivalent on topological residuated lattices. Then we prove that for every infinite cardinal number $alpha$, there exists at least one nontrivial Hausdorff topological residuated lattice of cardinality $alpha$. In the follows, we obtain some conditions on (semi) topological residuated lattices under which this spaces will convert into regular and normal spaces. Finally by using of regularity and normality, we convert (semi)topological residuated lattices into metrizable topological residuated ‎lattices.‎Fri, 30 Jun 2017 19:30:00 +0100Pseudoconvex Multiobjective Continuous-time Problems and Vector Variational Inequalities
http://ijim.srbiau.ac.ir/article_10639_1731.html
In this paper, the concept of pseudoconvexity and quasiconvexity for continuous~-time functions are studied and an equivalence condition for pseudoconvexity is obtained. Moreover, under pseudoconvexity assumptions, some relationships between Minty and Stampacchia vector variational inequalities and continuous-time programming problems are presented. Finally, some characterizations of the solution sets of a single-valued continuous-time programming problem are ‎obtained.‎Fri, 30 Jun 2017 19:30:00 +0100A Piecewise Approximate Method for Solving Second Order Fuzzy Differential Equations Under ...
http://ijim.srbiau.ac.ir/article_10640_1731.html
In this paper a numerical method for solving second order fuzzy differential equations under generalized differentiability is proposed. This method is based on the interpolating a solution by piecewise polynomial of degree 4 in the range of solution. Moreover we investigate the existence, uniqueness and convergence of approximate solutions. Finally the accuracy of piecewise approximate method by some examples are ‎shown.‎Fri, 30 Jun 2017 19:30:00 +0100
