  • Debebe, Wubshet (Addis Ababa University, 2019-07-05)
    This paper is concerned with harmonic function and partial di erential equation. Harmonic functions are regarded as solutions of Laplace equation which have a number of properties that are essential in solving partial ...
  • Mekonnen, Bezuneh (Addis Ababa University, 2018-09-01)
    In this paper, heat equation is derived using Fourier’s law of heat conduction and conservation of energy. In addition to this two laws Greens and divergence Theorem are used to change or transform line integral in to ...
  • Ebrahim, Haider (Addis Ababa University, 2017-05-17)
    In 1936 Hecke proved a correspondence theorem between Dirichlet series with functional equations and automorphic forms with certain growth conditions. In this correspondence, the Dirichlet series has at most simple poles ...
  • Debela, Oluma (Addis Ababa University, 2018-09-01)
    In this thesiswe study two important families of polynomials calledHermite and Laguerre polynomials. These special functions, like so many others functions arise as solutions of ordinary differential equations and have ...
  • Hagos, Kaleay (Addis Ababa University, 2018-08-12)
    In this project we study various solution techniques of Hermite differential equations, properties of Hermite polynomials and physical application of Hermite equations and Hermite polynomials to quantum harmonic oscillator.
  • Birhanu, Moges (Addis Ababa University, 2013-02)
    The Hille - Yosida Theorem is one of the most useful tools in the study of existence of a unique solution for evolution problem i.e., 8< Du+au=0 Dt(0)=u0 + Au = 0; on [0;+1); u(0) = u0; where A is a maximal monotone ...
  • Awgchew, Tesfaye (Addis Ababa University, 2011-01)
    In this work our definition of Semiring is given without zero 0 and unity 1. The focus of the study is to give appropriate evaluation on Semirings which have their own related properties with Distributive lattices. We prove ...
  • Baye, Alemu (Addis Ababa University, 2017-08)
    In this project the notion of an ideal of a lattice ordered monoid A is introduced. The notion of congruence relations on a lattice ordered monoid (l-monoid) A is also introduced and its relation with ideals of A is ...
  • Wondwoson, Betelehem (Addis Ababa University, 2016-07)
    Malaria is a mosquito-vectored infectious disease, which causes serious human health problems in many endemic areas. The dominant malaria vectors in sub-Saharan countries are Anopheles gambiae, Anopheles coluzzii, Anopheles ...
  • Negussie, Eshetu (Addis Ababa University, 2015-01)
    This study aimed to find out the current status of the implementation of CA, the attitude of teachers and students toward CA and the challenge facing the implementation of CA. The study involved 6 general secondary schools ...
  • Gerba, Desalegn (Addis Ababa University, 2014-12)
    The major objectives of this study were to investigate practices of active learning, to assess the implementation of Active learning approach and to identify factors affect the implementation of active the active learning ...
  • Tsegaye, Temesgen (Addis Ababa University, 2011-06)
    Fixed Charge Network Flow Problem (FCNFP) is a well known NP-hard problem. It has a wide spectrum of applications. Among them are problems in network design, scheduling, production planning, supply chain and transportation ...
  • Shimelis, Biniyam (Addis Ababa University, 2011-01)
    The most important in the theory of harmonic functions is that of finding a harmonic function with given boundary values; it is known as the Dirichlet problem. The Dirichlet problem consists in determining all regionsG ...
  • Gebrehiwot, Kibrom (Addis Ababa University, 2011-01-25)
    The purpose of this study is an attempt to explore sufficient condition for the convergence of Riemann integrable functions on any positive linear functional. The Arzela dominated convergence theorem holds for the Riemann ...
  • Kemal, Kiflu (Addis Ababa University, 2017-06)
    The methods that we describe presently, attempt to approximate a constrained optimiza- tion problem with an unconstrained one and then apply standard search techniques such as exterior penalty function method and interior ...
  • Shigute, Wodefit (Addis Ababa University, 2014-08)
    In this project paper we investigated solution for interior Dirichlet problem as main parts. First, we showed uniqueness and continuity of Dirichlet problem in bounded region using maximum and minimum principle. Next, ...
  • Melese, Getahun (Addis Ababa University, 2019-06-03)
    In this work we investigate the invertibility of single layer potential operator in 2D. The single layer potential operator contains non trivial kernel. Consequently, we need to set conditions on the domain or the space ...
  • Woldie, Wondimu (Addis Ababa University, 2017-04-20)
    The existence and iterative approximation offxed points of single- valued and multi-valued mappings in modular function spaces have been studied by many well known Mathematicians. Due to its appli- cability in real world ...
  • Mohammed, Jemal (Addis Ababa University, 2011-01)
    Ordered trees are trees with a distinguished vertex called the root where the children of each internal vertex are linearly ordered. K-trees generalize ordered trees in the sense that ordered trees are 2-trees in which ...
  • Atlaw, Tesfu (Addis Ababa University, 2015-03)
    A graph is said to be planar if it can be drown in the plane so that no two edges intersect except (possibly) at their ends vertices.It is of practical interest to able to determine whether a graph is planar or not, our ...
