ABSTRACT:

For any (p ,q) graph G,a subdivision graph S(G) is obtained from G by subdividing each edge of G. The regular number of a S(G) is the minimum number of subsets into which the edge set of S(G) should be partitioned so that the subgraph induced by each subset is regular and is denoted by (G) . In this paper some results on regular number of (G) were obtained and expressed in terms of elements of G.

KEYWORDS: subdivision graph

Almost relative strongly M –flat modules

M.R.ALONEY and GOVIND SAHU
(Research Scholor) Bhagwant University Ajmer, Raj. (India)

ABSTRACT:

Throughout this paper we have defined a new concept of almost
strongly M-flat modules11 and we are motivated10. And given several
properties of them13. This paper concept introduced as a generalization
of flat modules.
There are two part in discussion
In first part we study Almost strongly M-flat modules and in
second section we study about the homomorphism
( , )→ ( )
Where A is an R-algebra, XJ and NJ is R-modules.
And last result we prove M be almost strongly M-flat modules
then following statement are equivalent.
a) Any finitely generated ideal I is almost M-projective
b) Every submodule of M is almost strongly M-flat modules.
c) Every flat module is almost strongly M-flat module.

ABSTRACT:

In this paper, we generalize the concepts of pseudo weaklyinjective (PW-injective for short) modules and weakly-finitely-quasiinjective (WFQ-injective for short) modules to pseudo-weakly-finitelyquasi- injective (PWFQ-injective for short) modules.

Symmetry in Plane

1Department of Mathematics, CU Shah University, Wadhwan City-363 030 Gujarat (India)
2Department of Mathematics, Gujarat University Ahmedabad-380 009 Gujarat (India)

ABSTRACT:

In this article we study symmetries of plane figures. We start with the definition of isometry of a metric space. For the better understanding of all the isometries of R2, we present the known results in form of a flow chart. And then using this idea of isometry, we define symmetry group of a subset of R2. With the use of this definition we determine symmetry groups of the capital Alphabets of English. We also describe the symmetry group of a regular n-gon which is known as
Dn. We also describe subsets of R2 where symmetry group is the cyclic group of order n which is denoted usually by Cn
