چکیده
where Re means "real part. " It is easy to see that P(x) is the time rate of change at which the electric field does work per unit volume on the sources. Hence S'= (1/Ssr) g;lb;*lb; is the energy density and the components S' (a=1, 2, 3) are the components of the Poynting vector. Since the field P is arbitrary, we can strip off the integrals in (9) and obtain the familiar diGerential form of the conservation of energy:

Symmetry group, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation
In this paper Lie point symmetries, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation are investigated. First of all Lie symmetries are obtained by using the general method based on invariance condition of a system of differential equations under a prolonged vector field. Then the structure of symmetry ...
متن کاملOn Black-Scholes equation; method of Heir-equations, nonlinear self-adjointness and conservation laws
In this paper, Heir-equations method is applied to investigate nonclassical symmetries and new solutions of the Black-Scholes equation. Nonlinear self-adjointness is proved and infinite number of conservation laws are computed by a new conservation laws theorem.
متن کاملON SYMMETRY IN MODERN PHYSICS (Dedicated to the 100th anniversary of the birth of Academician V.A.Fock)
The development of the gauge symmetry has resulted in a complete determination of the Lagrangians for electromagnetic, weak, strong and gravitational interactions and has created illusions about the construction of ®the theory of everything ̄. However, in just the same way as in classical physics, it became clear that the deductive obtaining of solutions (laws of Nature) is based not only on the...
متن کاملInteractions of Islamic Republic of Iran
The process of decision making about geopolitical interactions either has a public source and receives its legitimacy and legality from people and public arena or decisions are made and strategies are chosen by official institutions and political elites beyond the volition of public arena. Based on this fact, the current article tries to answer this question that what is the source of legitimac...
متن کاملSymmetries and Unification
Symmetries concerning the ordinary coordinate spacetime and internal spacetime are discussed. A possible unification model of elec-troweak, strong and gravitational interactions is briefly described. Symmetry has played a crucial role in physics. I first learned the importance of symmetries in physics was from the lecture talks given by professor C.S. Wu when I was a student in the Department o...
