Order Structures of One-point Extensions of Locally Compact Spaces

Abstract For a locally compact space, we define an order-anti-isomorphism from the set of all one-point extensions of onto the set of all nonempty closed subsets of . We consider various sets of one-point extensions, including the set of all one-point locally compact extensions of , the set of all one-point Lindelöf extensions of , the set of all one-point pseudocompact extensions of , and the set of all one-point Cech-complete extensions of , among others. We study how these sets of one-point extensions are related, and investigate the relationship between their order structure, and the topology of subspaces of , we also study the relationship between various subsets of one-point extensions, the existence of minimal and maximal elements in various sets of one point extensions, and we show how some of our results may be applied to obtain relations between the order structure of certain subfamilies of ideals of partially ordered with inclusion, and the topology of subspaces of .

مؤثرات كازيمير وتطبيقاتها

في هذه الدراسة نقدم مؤثرات كازيمير ونعرج على أهميتها كأداة رياضية تستعمل في المجالات التطبيقية وخصوصا في الفيزياء قبل ذلك نعطي نبذة جيدة عن جبرلي والذي يفترض بأنه جبر المبادلات ثم نربط بين ذلك وبين مؤثرات كازيمير.كتطبيق واضح في هذا الاتجاه، ندرس مؤثرات الزخم الزواي وعلاقاتها التبديلية وفي الختام نعطي بعض الأمثلة على تطبيقات مؤثر كازيمير . Abstract In this study, we introduce Casimir operators and their importance as a mathematical tool to be used in applied fields, especially in physics. Before that we give a good account on Lie algebra which is supposed to be the algebra of commutators and then we relate this to Casimir operators. As an obvious application in this concern we study angular momentum operators and their commutation relations. Finally we give some examples on the applications of the Casimir operator .

On the System of Nonlocal and Nonlinear Elliptic Boundary Value Problems

في هذا العمل قمنا بدراسة نظريات الوجود والوحدانية على المعادلات التفاضلية الجزئية مع الشرط الحدي اللامحلي من النوع الناقصية وأنظمتها من الرتبة الثانية في المجال الثالث. حيث قدم هذا العمل في أربعة فصول في الفصل الأول والثاني قمنا بتجميع التعريفات والنظريات الهامة التي استخدمناها في الفصل الثالث والرابع اللذين احتويا على النتائج الرئيسية لهذا العمل. حيث أننا في الفصل الثالث قمنا بدراسة مسألة القيمة الحدية اللامحلية لمعادلة تفاضلية جزئية ناقصية.وفي الفصل الرابع حاولنا تعميم المسألة السابقة إلى منظومة من المعادلات الناقصية مع الشروط الحدية اللامحلية من النوع الثالث. Abstract In this work, we have studied the theories of existence and solitariness on the subtracted partial differential equations and their second degree systems in the field of with the third type nonlocal minimum condition. This work introduced in four chapters. In the first and second chapters, we have gathered vital definitions and theories which we have used in the third and forth chapters which contained the main results of this work.In the third chapter, we have analyzed the nonlocal minimum value question of a subtracted partial differential equation.In the forth chapter, we have tried to generalize the previous question to a system of subtracted equation with the third degree type non-local minimum conditions.
