We introduce the concepts of general n-ary hyperstructure semilattice ( or gnh-semilattice) and Gnh-subsemilattice, ideal of gnh-semilattice, gno-order, Gnoorder, multiplier of type α on gnh-semilattice, F-quasi invariant subset of gnh-semilattice and so on. We also study some of their related properties.https://jhs.uma.ac.ir/article_2608_d18f5f6a5bc97b9e811475634c63fb21.pdfUniversity of Mohaghegh ArdabiliJournal of Hyperstructures2251-84365120160601Some results on PIT and GPIT theorems1725265010.22098/jhs.2016.2650ENM.EbrahimpourDepartment of Mathematics, Vali-e-Asr University of Rafsanjan, P.O.Box 518, Rafsanjan, IranJournal Article20160224In this paper we generalize the P IT and the GP IT that can be used to study the heights of prime ideals in a general commutative Noetherian ring R and the dimension theory of such a ring and we use these generalizations to prove some useful results. https://jhs.uma.ac.ir/article_2650_fde4ff909cebfab9417b0668a93d0b4b.pdfUniversity of Mohaghegh ArdabiliJournal of Hyperstructures2251-84365120160601On harmonious chromatic number of triple star graph2632265110.22098/jhs.2016.2651ENAkhlakMansuriDepartment of Mathematics, Lakshmi Narain College Of Technology (LNCT, Bhopal),

Iran.Journal Article20160125This paper proposed a reproducing kernel method for solving Wiener-Hopf equations of the second kind. In order to eliminate the singularity of the equation, a transform is used. The advantage of this numerical method is the representation of exact solution in reproducing kernel Hilbert space and accuracy in numerical computation is higher. On the other hand, by improving the traditional reproducing kernel method and the definition of the operator of W Hilbert space, the solutions of Wiener Hopf equation of the second kind are obtained. The approximate solution converges uniformly and rapidly to the exact solution. Numerical examples indicate that this method is efficient for solving these equations. The validity of the method is illustrated with two examples.https://jhs.uma.ac.ir/article_2654_c5cb7242e2f5c1c3133862091004f294.pdfUniversity of Mohaghegh ArdabiliJournal of Hyperstructures2251-84365120160601Differential transformation method for solving hybrid fuzzy differential equations6983265510.22098/jhs.2016.2655ENBahmanGhazanfariDepartment of Mathematics, Lorestan University, P.O.Box 68137-17133, Khorramabad, IranParvinEbrahimiDepartment of Mathematics, Lorestan University, P.O.Box 68137-17133, Khorramabad, IranJournal Article20150122In this paper, Differential Transformation Method (DTM) was studied for solving Hybrid Fuzzy Differential Equations (HFDEs).
