Multi-Presheaves and Multi-Sheaves Constructions
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 1
In this paper, we modify the classical theory of sheaves, in such a way that it includes applications where more than one restriction map between sections are needed, we also show how the class of multi-presheaves on a topological space may be made into a category, with suitable notion of morphisms based on a generalization of natural transformation. Several examples are given. ...

Certain New Subclasses of Analytic Univalent Functions in the Unit Disk
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 1
Introduction of new subclasses and of analytic functions with negative co-efficents defined in the unit disk. We estimate some properties of functions in these classes and obtain Co-efficient bounds, Neighbourhood and Integral means inequality for the function f(z) under these classes. ...

A Study on New Sequence of Functions Involving the Generalized Contour Integral
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 1
The aim of the present paper is an attempt to introduce a new sequence of functions { (M,N;P,Q,R; ) ( ) } n V x;a, k,s / n 0,1, 2,... α = in equation (1.15), which involving with the generalized contour integral M,N [ ] P,Q;R I x . By using operational technique, some interesting generating relations and finite summation formulae are obtained in sections 2 and 3. These generating ...

Uniform Strict Practical Stability Criteria for Impulsive Functional Differential Equations
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 1
Strict stability is the kind of stability that can give us some information about the rate of decay of the solution. There are some results about strict stability of functional differential equations. On other hand, in the study of stability, an interesting set of problems deal with bringing sets close to a certain state, rather than the equilibrium state. The desired state of a system m...

Modeling and Analysis of an SEIR Epidemic Model with a Limited Resource for Treatment
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 14
In this paper an SEIR epidemic model with a limited resource for treatment is investigated. It is assumed that the treatment rate is proportional to the number of patients as long as this number is below a certain capacity and it becomes constant when that number of patients exceeds this capacity. Mathematical analysis is used to study the dynamic behavior of this model. Existence and st...

A Class of Improved Estimators for Estimating Population Mean Regarding Partial Information in Double Sampling
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 14
In this paper a class of improved estimators has been proposed for estimating population mean in two phase (double) sampling when only partial information is available on either of two auxiliary variables. Under simple random sampling (SRWOR), expressions of mean square error and bias have been derived to make comparison of suggested class with wide range of other estimators. Empirical s...

The Effects of Thermal Radiation, Chemical Reaction and Rotation on Unsteady MHD Viscoelastic Slip Flow
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 14
This paper investigates the unsteady flow of an electrically conducting incompressible non-Newtonian viscoelastic fluid through a porous medium filled in a vertical porous channel in the presence of transverse magnetic field. The fluid and the channel rotate as a solid body with constant angular velocity, ð›€ð›€âˆ—, about an axis perpen...

INTUITIONISTIC L-FUZZY RINGS
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 14
In this paper we study some generalized properties of Intuitionistic L-fuzzy subrings. In this direction the concept of image and inverse image of an Intuitionistic L-fuzzy set under ring homomorphism are discussed. Further the concept of Intuitionistic L-fuzzy quotient subring and Intuitionistic L-fuzzy ideal of an Intuitionistic L-fuzzy subring are studied. Finally, weak homomorphism, ...
