APPLICATION OF - " THE VIRIAL METHOD TO THE SOLUTION OF SOME PROBLEMS < ' IN FLUID DYNAMICS
(Alneelain University, 2006) Mohamed Saad E1-Din Abdel Gafoor Abdel Magid
The problem of the charged spheroidal bubble is studied using the virial method. The conditions that are necessary for equilibrium are deduced and the oscillation of the bubble is studied . The frequencies belonging to the second order harmonics are found . Further extension of the virial theorem is made by studying the viscous ﬂuid sphere in an incompressible viscous ﬂuid giving the different and necessary virial equations of motion for both the exterior and the interior media and then the equilibrium state is studied.

THE GEOMETRICAL QANTIZATION OF PHYSICAL FIELDS
(Alneelain University, 2007-10) Khalid Masoud Makin Mohamed Ali
ABSTRACT We considered the problem of geometric quantization. We ﬁrst started with the classical symplectic geometry and then'we used the complex line bundle to describe prequantization and quantization. Geometrically the Hilbert space of quantum states is constructed from the sections of the complex line bundle over the phase space. We then used the invariance group approach to the geometric quantization.
