چکیده

In this paper, we consider a member of an integrable family generalized Camassa–Holm (GCH) equations. We make analysis the point Lie symmetries these equations by using method infinitesimals. derive nonclassical and find new via method, which cannot be obtained symmetry method. employ multiplier to construct conservation laws for GCH Using underlying equation, double reduction is also constructed. Finally, investigate traveling waves convergent series solutions both homoclinic heteroclinic orbits traveling-wave equations, correspond pulse front original respectively.

Symmetry Priniciples And Conservation Laws

Symmetry considerations provide an extremely powerful and useful tool in our efforts to discover and understand the order in nature. Gradually they have become the backbone of our theoretical formulation of the physical laws. One of the most important consequences of the existence of symmetry (or invariance) is that a corresponding conservation law, with a conserved charge, follows. We shall el...

Symmetry Principles and Conservation Laws

Newtonian physics is characterized by the existence of various conservation laws, that is, principles that tell us that however complicated the interactions among the components making up the system, certain quantities never change. Perhaps the most familiar such law is the conservation of the total mass of the system, or “amount of matter” in it: as described in Feynman, §3, we believe that in...

Conservation Laws and Symmetries of Generalized Sine- Gordon Equations

We study some systems of non-linear PDE's (Eqs. 1.1 below) which can be regarded either as generalizations of the sine-Gordon equation or as two-dimensional versions of the Toda lattice equations. We show that these systems have an infinite number of non-trivial conservation laws and an infinite number of symmetries. The second result is deduced from the first by a variant of the Hamiltonian fo...
