one of the most important and enduring questions in the sphere of political thought is the kind of the relationship between ethics and politics. the outcome of such a debate has led to the formation and development of different perspectives. while some scholars believe that there is a practical paradox between exercising effective political power and observing ethical principles, others assume ...

We generalize Birkhoff's Theorem in the following fashion. find necessary and sufficient conditions for any spherically symmetric space-time to be static terms of eigenvalues stress-energy tensor. In particular, we Tolman-Oppenheimer-Volkoff equation prove that theorem holds under weaker hypothesis no pressure (with respect an appropriate frame.) provide equations show how coefficients metric r...

In this course we will be studying the subgroup structure of the finite alternating and symmetric groups. What does the phrase “study the subgroups of symmetric groups” mean? In this introduction I’ll suggest an answer to that question, and attempt to convince you that answer has some merit. In the process you’ll get some idea of the material we will be covering, and I’ll attempt to motivate th...

INTRODUCTION The young adult age group is at the highest risk of road trauma [1]. Further, the motor vehicle crash (MVC) risk for young adult drivers typically increases with the presence of a passenger [2]. While traditionally road safety strategies have focused on changing the driver there may be considerable opportunity to improve safety by developing passenger safety interventions. In parti...

this paper gives a short survey of some of the known results generalizing the theorem, credited to i. schur, that if the central factor group is finite then the derived subgroup is also finite.

Due to the increasing growth of processing cores in complex computational systems, all the connection converted bottleneck for all systems. With the protection of progressing and constructing complex photonic connection on chip, optical data transmission is the best choice for replacing with electrical interconnection for the reason of gathering connection with a high bandwidth and insertion lo...
