CODEN: MSMADH LEFT DOUBLE DISPLACEMENT SEMIGROUP: A FIRST RESULT
Journal Title: Matrix Science Mathematic | Matriks Sains Matematik (MSMK) - Year 2018, Vol 2, Issue 2
Abstract
In the present article a new type of algebraic structures named as left double displacement semigroup (LDD-semigroup). The structure is enhanced toward its left double displacement group (LDD-group) and discovered some useful results about these structures. The name of the notion is due to double displacement reactions in chemistry because they have same pattern of elements arrangement.

Jackknife Replication Variance Estimation of Population Total Under Systematic Sampling With Varying Probabilities
Systematic sampling with probability proportional to size either randomized or non-randomized, has been used in a number of large scale household survey. Even this sampling technique has been widely used in forestry for...
EXISTENCE OF POSITIVE SOLUTIONS TO A COUPLED SYSTEM OF FRACTIONAL HYBRID DIFFERENTIAL EQUATIONS
In this article, we investigate existence and uniqueness of positive solution to coupled system of Caputo's boundary value problem for fractional order differential equations of the form
MULTIGRID SOLUTION FOR THE CAUCHY PROBLEM ASSOCIATED WITH HELMHOLTZ TYPE EQUATION ON NON-UNIFORM GRIDS
In this paper, an HOC scheme with multigrid algorithm is developed for solving the Cauchy problem associated with two dimensional Helmholtz type equations. The suggested scheme has up to fourth order accuracy. Lastly, so...
EXISTENCE RESULTS TO A CLASS OF HYBRID FRACTIONAL DIFFERENTIAL EQUATIONS
This article is devoted to the study of existence results to a class of boundary value problems for hybrid fractional differential equations. A couple of hybrid fixed point theorems for the sum of three operators are use...
