Abstract: Let R be a commutative ring with identity and M be a module over R . The set of all maximal submodules of M is denoted by Max(M) . The Rmodule M is said to be a M - top R - module if Max(M) has a Zariski topology .The main purpose of this thesis, is to study when Zariski topology on Max(M) exists and study the relationship between the topological properties of the space Max(M) and the topological properties of an Rmodule M . In addition, the compactness , connectedness , strongly connectedness , locally compact , locally connected , HK - space and the separation axioms will be shown .From the main results which have been got , if M is a multiplication faithful finitely generated R - module, then Max(M) and Max(R) are homeomorphic . Also the study will prove if M is a multiplication Rmodule then M is semi - local if and only if Max(M) is an HK - space . Moreover , it would be proved that if M is a multiplication Rmodule , then M is semi - simple if and only if Max(M) is a disconnected space under a certain condition .Also , it would be stated that for any M - top R - module , M is a local module if and only if Max(M) is strongly connected .Also , it would be proved that for a multiplication R - module , if M is an F - regular ,then Max(M) is a regular space .

Abstract: Let U denote the unit ball in the complex plane, the Hardy space H2 is the collection of functions Σ f (z) f ^ (n)zn holomorphic on U suchthat f ^ (n) with f (n) ^ denotes then the Taylor coefficient of f, where the norm is defined by ) n ( f f Σ The particular importance of H2 is due to the fact that it is a Hilbert space. Let φ be a holomorphic self - map of U, the composition operator Cφ induced by φ is defined on H2 by the equation C f = f φ (f ∈H2 ) φ o We have studied the composition operator induced by the special automorphism p α and discussed the adjoint of the composition of the symbol p α .We have look also at some known results on compositionoperators and tried to see the analogue results in order to show how the results are changed by changing the point p in U.In order to make the work accessible to the reader, we have included some known results with the details of the proofs for some cases and proofs for the results that once given in the literature with proofs.Finally, we hope that this will show that there is a lot of work that can be done in the area of composition operator.

The proposed methods are classified as indirect and direct methods. The indirect methods are usually based on the necessary optimality conditions. Besides necessary conditions, sufficient condition has to be checked to ensure the optimality of the solution. The result by applying these conditions is a two point boundary value problem (TPBV). The direct methods in our work is employed by using state vector parameterization (SVP) technique to convert the QOC problem into a quadratic programming problem. Here the state vector parameterization is based on different basis functions to approximate the system state variables by a finite length of the basis functions series of unknown parameters.This thesis presents proposed numerical algorithms including : sigle - step methods (SS) (Euler method and modified Euler methods) and sigle - step extrapolation method (SSE) with the aid of Euler method and modified Euler methods which are classified within the indirect methods to solve some QOC problems. In addition, three modified algorithms which are depending on SVP technique including : state vector parameterization with Laguerre polynomials (SVPL), state vector parameterization with Hermite polynomials (SVPH) and state vector parameterization with Laguerre functions (SVP ) to solve the finite and infinite time quadratic performance indices subject to the system state variables. The use of Laguerre and Hermite polynomials as well as Laguerre functions is new. Some important formulas are derived and proved which are essential in these methods. Furthermore, in this work very efficient algorithms are proposed which are based on applying the idea of spectral method using power series, Laguerre polynomials, Hermite polynomials and Laguerre functions, as abasis functions, to give the methods SMP, SML, SMH and SM respectively. To facilitate the computations, new properties of power series, Laguerre polynomials, Hermite polynomials and Laguerre functions called differentiation operational matrices are derived. Additionally, the proposed algorithms have been applied for several examples. We find that the proposed methods produce better or comparable results to that given in [9], [25], [27], [49] and [50].

Abstract: The main aim of this work is to solve the partial differential equations of second order with constant coefficients which have three independent variables (x , y , t) of the general form : AZ + BZ + CZ + DZ + EZ + FZ +GZ + HZ + IZ + JZ = 0 xx xy xt yy yt tt x y t where A , … , J are real constants . We found that the substitution = ∫ ∫ ∫ U x dx+ V y dy+ W t dt x y t e transforms the above equation to the first order ordinary differential equations with three independent variables which have the general form : F W t W t GU x HV y IW t J A U x U x BU x V y CU x W t D V y V y EV y W t For this purpose , the above partial equation is classified to many cases depending on the values of A, B,K, J . Each case is divided into many other cases , giving the general forms of allcases of the solutions . Some of the solutions are proved , leaving others whose proofs are similar to each other .
