المستخلص: في هذه الرسالة قمنا باستخدام مفاهيم المجموعة الصفرية (يقال للمجموعة A انها صفرية في X اذا كانت A = f - 1(0) حيث ان f دالة مستمرة ذات قيم حقيقية على الفضاء التبولوجي X) ومتممة المجموعة الصفرية والمجموعة المفتوحه من النمط Z، وذلك لتعريف انماط جديدة من بديهيات الفصل يقال لها بديهيات الفصل من النمط Z والتي هي Z - Ti حيث ان i = 0,1,2,3,4 مع بديهيتي الفصل الاعتيادية من النمط Z (Z - R) والطبيعية من النمط Z (Z - N). لقد استخدمنا المجموعات المفتوحة من النمط Z في بديهيات الفصل Z - Ti لغرض فصل العناصر المختلفة والمجموعات المنفصلة. لقد درسنا في هذا العمل خواص الفضاءات من الانماط Z - Ti وعلاقاتها مع الفضاءات المعروفة من الانماط Ti وعلاقاتها مع بعضها البعض معززة بالبراهين والامثلة. لقد سلطنا الضوء على بديهية الفصل Z - T2 لانها تلعب دورا مهما في التبولوجيا العامة وعلى وجه الخصوص في التقارب. ولهذا قمنا بتعريف التقارب من النمط Z كما درسنا هذا النوع من التقارب في الشبكات والفلاتر في الفضاءات من النمط Z - T2. ومن المعروف من ناحية اخرى ان التراص واحدة من المفاهيم المهمة في التبولوجيا العامة، لذا درسنا مفهوم التراص من النمط Z وهو نوع من التراص اضعف من مفهوم التراص الاعتيادي وقد تمت الدراسة باستخدام مفهوم المجموعات المفتوحة من النمط Z كغطاء للفضاء التبولوجي. تكون اهمية الفضاء التبولوجي مضاعفة اذا كان يحقق التراص من النمط Z وكذلك يحقق بديهية الفصل Z - T2. | In this thesis, we use the concepts of zero set (A set A is called a zero set of X if A = f - 1(0) where f is a real valued continuous function on any topological space X), cozero set, and Z - open set to define new types of seperation axioms called Z - separation axioms, which are Z - Ti axioms where i = 0,1,2,3,4 with Z - regular (Z - R) and Z - normal (Z - N) axioms. We used Z - open sets in Z - Ti spaces in order to separate different points and disjoint sets. In this work we studied the properties of Z - Ti spaces, its relations with the known Ti spaces, and the relations between each other with proofs and counter examples. We fox on Z - Ti axioms, since it plays an important role in general topology and especially in covergence, so we defined the Z - convergence and studied it in nets and filters in Z - Ti spaces. On the other hand it is known that compactness is one of the important concept of general topology, so we studied the concept of Z - compactness which is a weak kind of compactness using Z - open sets as a cover for the topological space. If a topological space is Z - T2 and Z - compact space, then it is doubly important

المستخلص: No one disagrees that literature mostly is manufactured by events influences by them and affect them at the same time ,so it was coherent for these events special in a country like Al - andalous ,who had faced enchants and catastrophes for the eight centuries.The turbulent political events that overrun Alandalous during the Almuwahdeen and Bani Alahmar era had teemed in the finest of litterateurs ,and it was an important stream to praise the National trend and raise the religious motive. All that was clear through convoying literature using poetry and prose. Some of the participated in fighting really, and they support Almujahdeen to defend on their cities in fighting field, and some of them were busy with literature only screaming or urging or imaging the battles without participating really in and some of them were singing for conquest in case of victory.We decided that the plan of the research should draw the characteristics of catastrophe and touching its echo painted by this division.In preface, we stopped on the catastrophes steps in both ,the political and social life, with pause of the main events that happened in Amuwahdeen and Bani Alahmar states showing their influence on the catastrophe, and mentioning the main battles that had happened and its influence on Andalusia catastrophe. We also discussed the history of Arts Prose cross ages that preceded the study age ,and showing the concept of catastrophe and tragedy linguistically and idiomatically .Whereas ,chapter one was the vessel that comprehend the objective study for the prose of the catastrophe, and many phenomena stopped us, and the necessity to showing them up such as Alestsrakh, panegyric of cities, describing the tools of the war ,compliment poetry of conquest and victory. With serious pause of compliment for martyrs (leaders, princes).Chapter two discussed the sentimental dimensions for the catastrophe. We mean the reflection of catastrophe on the public sentiment ,people in general and the creators of writers in private. The result was Asceticism poetry ,Mysticism and praising the prophet, Alienation and Nostalgia after forced migration for the people of Al - Andalous.bChapter three focused on the Artistic touches ,so the function of the researcher is trying to find the hidden Art behind the prose text ,that may be it will find its lost creation that is called the elegant Art.The flashes of Art stopped us ,so we tried to decode the language and style based on curriculum that studies the language to explore the passionate and emotions, stir emotions, influencing on human behavior being a tool that the creator reaches to the meaning.Another study about the tendency of short story ,and our tries to grab the beginnings of this Art, and how the writer employing this tendency in the catastrophe texts to focus on the courage and heroism values, and pay attention to the reason of Jihad.The second Artistic picture, that we believe it represents an external image to decorate creation and nearing content for the receiver. So ,our duty in this study is to investigate the positions of picture in prose, which is it out of the path of critical styles, and believe that critical Artistic picture is kind of aspect in poetry.We ended our research with a conclusion that we summarized the main results that showed up during the research : The research has filled some space in the Andalusia Literature specially prose, which has draw our attention and will draw the others attention to the necessity to study the Jihad's glimmers in Andalousosia by availability of prose texts.
