In this work, we look at the connection between Young tableaux and sym- metric group representations. The design of Specht is discussed in detail. Two noteworthy ndings presented and followed by instances are modules that ...
In this project paper, works on q-Riordan matrices, their algebraic structures and applications on some famous numbers like the q-Striling and q-Bessel numbers have been studied and reported.
In this project report, explicit nite di erence scheme for 2D parabolic par- tial di erential equations is considered. This method is used to solve the partial derivatives in the partial di erential equations at each ...
Constrained optimization problems are relatively more complex than uncon- strained optimization problems. Some of these complexities are minimized by penalty and barrier methods. Penalty and barrier methods are ...
Quadratic programming is one of the type of nonlinear optimization problems in which the objective function is quadratic and all the constraints are linear. There is no single method available for solving a quadratic ...
Stockout cost is the cost that happen when the demand is greater than the inventory. It may be either back order cost or lost sale cost. Generally inventory problems has many features and cases. I formulate a probabilis- tic ...
Mixed integer programming is a linear programming with some of the deci- sion variables are integer and some of them are continuous. Thus, unlike to linear programming it some what complex to solve due to the integer ...
This paper is concerned with Analysis of heat equation in Rn. Analysis of heat equation in Rn regarded as Fourier Transformation which has di erent properties and Inverse of Fourier Transformation that is important to ...
A game with two rational players in which the gain payo for one is loss for the other is called two person zero-sum game. i.e the sum of payo s for the two players are zero. Two person zero-sum game with nite sets of ...
This project provides a practical overview of numerical solutions to the linear one dimensional Advection equation using finite difference method. It presents a number of schemes for solution of Linear Advection equation, ...
Molecular descriptors called topological indices are graph invariants that play a signi_cant role in chemistry, materials science, pharmaceutical sciences and engineering, since they can be correlated with a large number ...
Mathematical optimization is the process of maximizing or minimizing an objective function by _nding the best available values across a set of inputs under a restriction domain. This project focuses on _nding the optimality ...
In this dissertation, the boundary value problems (BVPs) for the second order elliptic partial differential equation with variable coefficient in two-dimensional bounded domain is considered. Using an appropriate parametrix ...
In this thesis, certain in_nite subsets of the set of positive integers are inves- tigated as possible spectra of regular weighted Sturm-Liouville eigenvalue problem with separated homogeneous boundary conditions. With ...
A Parking function is a sequence of positive integers (a1; a2; : : : ; an) such that its non-decreasing rearrangement (b1; b2; : : : ; bn), satis es bi i, for all index i. In this thesis we will see about parking ...
The FBI transform is a nonlinear Fourier transform that characterizes the local/ microlocal smoothness and analyticity of functions (or distributions) in terms of appropriate decays. This characterization is very useful ...
In the field of science and engineering, researches often come across with problems model by system of nonlinear algebraic equations that cannot solve easily. Numerical convergence for many problems, typically solved by ...
We introduce the notion of Weak idempotent ring (WIR, for short) which is a ring of characteristic 2 and a4 = a2 for each a in the ring. We obtain certain properties of this class. Further we provide examples of weak ...
