Abstract: Recently the unified method for finding traveling wave solutions of non-linear evolution equations was proposed by one of the authors a. It was shown that, this method unifies all the methods being used to find these solutions. In this paper, we extend this method to find a class of formal exact solutions to Korteweg-de Vries (KdV) equation with space dependent coefficients. A new class of multiple-soliton or wave trains is obtained.
Keywords: Exact solution, Extended unified method, Korteweg-deVries equation, variable coefficients

Abstract:A self- starting hybrid linear multistep method for direct solution of the general second-order initial value problem is considered. The continuous method is used to obtain Multiple Finite Difference Methods (MFDMs) (each of order 7) which are combined as simultaneous numerical integrators to provide a direct solution to IVPs over sub-intervals which do not overlap. The convergence of the MFDMs is discussed by conveniently representing the MFDMs as a block method and verifying that the block method is zero-stable and consistent. The superiority of the MFDMs over published work is established numerically.

Abstract:This paper deals with the determination of thermal stresses in a thin clamped hollow disk under unsteady temperature field due to point heat source situated at centre along radial and axial direction within it. A thin hollow disk is considered having arbitrary initial temperature and is subjected to arbitrary heat flux at the outer circular boundary; whereas inner boundary is at zero heat flux. Also, the upper and lower surfaces of the disk are at zero temperature. The inner and outer edges of the disk are clamped. The governing heat conduction equation has been solved by the method of integral transform technique. The results are obtained in a series form in terms of Bessel's functions. The results have been computed numerically and illustrated graphically.

Abstract: As generalization of the fractional Cosine transform (FRCT), the Canonical Cosine Transform (CCT) has been used in several areas, including optical analysis and signal processing. For practical purpose half canonical cosine transform is more useful. Hence in this paper we have proved some important results Differentiation property, Modulation property, Scaling property, Derivative property, Parseval's Identity for half canonical cosine transform (HCCT).

Abstract: The Airy stress function for a vertical dip-slip line source buried in a homogeneous, isotropic, perfectly elastic half-space with rigid boundary is obtained. This Airy stress function is used to derive closedform analytical expressions for the stresses and displacements at an arbitrary point of the half-space caused by vertical dip-slip line source. The variation of the displacements and stress fields with distance from the fault and depth from the fault is studied numerically.

Abstract: Graph Theory has been realized as one of the most flourishing branches of modern Mathematics finding widest applications in all most all branches of Sciences, Social Sciences, Engineering, Computer Science, etc. Number Theory is one of the oldest branches of Mathematics, which inherited rich contributions from almost all greatest mathematicians, ancient and modern. Using the number theoretic function Euler totient function we have defined an Euler totient Cayley graph and in this paper we study the Clique domination parameters of Euler totient Cayley graphs.

Abstract: We prove that every finite subspace generated by the linearly ordered idempotent elements in an incline has a unique standard basis. This leads to every finite subspace of a regular incline whose elements are all linearly ordered has a unique standard basis and thereby we disprove the result of Cao that is "Every subspace of a finite incline whose idempotent elements are linearly ordered has a unique standard basis". As an application we exhibit that under certain conditions each vector in a finitely generated subspace of a vector space has a unique decomposition as a linear combination of the standard basis vectors.

Abstract: In this paper, we prove common flexed point theorems for semi-compatible mappings on intuitionistic fuzzy metric space with different some conditions of Park and Kim ([10], 2008). This research extended and generalized the results of Singh and Chauhan ([14], 2000). The concept of fuzzy set was developed extensively by many authors and used in various fields. Several authors have defined fuzzy metric space Kramosil and Michalek(([5],1975) etc.) with various methods to use this concept in analysis. Jungck (([3],1986), ([4],1988)) researched the more generalized concept compatibility than commutativity and weak commutativity in metric space and proved common fixed point theorems, and Singh and Chauhan ([14],2000) introduced the concept of compatibility in fuzzy metric space and studied common fixed point theorems for four compatible mappings.

In the present paper we obtain necessary and sufficient conditions and some important properties for the analytic functions for its belongingness to certain class of functions. The distortion inequalities, closer theorems, radii of close-to-convexity, radii of starlikeness and radii of convexity are obtained for the same class of functions. Some properties involving Hadamard product are also obtained

Abstract: An introduction to Fourier Series and Fourier Transform is the topic of this paper. It deals with what a Fourier Series means and what it represents. The general form of a Fourier Series with a provision for specific substitution has also been mentioned. The paper also includes a brief overview of Fourier Transform. The use of Fourier Transform to convert a time domain function into a frequency domain equivalent has also been shown. A method of converting the continuous Fourier Transform into a discrete form and thus obtaining the Discrete Fourier Transform has also been discussed. A few practical life application of Fourier analysis have been stated.
