Equation Mathematical Physics

INTRODUCTORY APPLICATIONS OF PARTIAL DIFFERENTIAL EQUATIONS With Emphasis on Wave Propagation and Diffusion This is the ideal text for students and professionals who have some familiarity with partial differential equations, and who now wish to consolidate and expand their knowledge. Unlike most other texts on this topic, it interweaves prior knowledge of mathematics and physics, especially heat conduction and wave motion, into a presentation that demonstrates their interdependence. The result is a superb teaching text that reinforces the reader's understanding of both mathematics and physics. Rather than presenting the mathematics in isolation and out of context, problems in this text are framed to show how partial differential equations can be used to obtain specific information about the physical system being analyzed. Designed for upper-level students, professionals and researchers in engineering, applied mathematics, physics, and optics, Professor Lamb's text is lucid in its presentation and comprehensive in its coverage of all the important topic areas, including: One-Dimensional Problems The Laplace Transform Method Two and Three Dimensions Green's Functions Spherical Geometry Fourier Transform Methods Perturbation Methods Generalizations and First Order Equations In addition, this text includes a supplementary chapter of selected topics and handy appendices that review Fourier Series, Laplace Transform, Sturm-Liouville Equations, Bessel Functions, and Legendre Polynomials.

The main topics reflect the fields of mathematics in whichProfessor O.A. Ladyzhenskaya obtained her most influentialresults.One of the main topics considered in the volume is the Navier-Stokesequations. This subject is investigated in many different directions.In particular, the existence and uniqueness results are obtained forthe Navier-Stokes equations in spaces of low regularity. A sufficientcondition for the regularity of solutions to the evolutionNavier-Stokes equations in the three-dimensional case is derived andthe stabilization of a solution to the Navier-Stokes equations to thesteady-state solution and the realization of stabilization by afeedback boundary control are discussed in detail. Connections betweenthe regularity problem for the Navier-Stokes equations and a backwarduniqueness problem for the heat operator are also clarified.Generalizations and modified Navier-Stokes equations modeling variousphysical phenomena such as the mixture of fluids and isotropicturbulence are also considered. Numerical results for theNavier-Stokes equations, as well as for the porous medium equation andthe heat equation, obtained by the diffusion velocity method areillustrated by computer graphs.Some other models describing various processes in continuum mechanicsare studied from the mathematical point of view. In particular, astructure theorem for divergence-free vector fields in the plane for aproblem arising in a micromagnetics model is proved. The absolutecontinuity of the spectrum of the elasticity operator appearing in aproblem for an isotropic periodic elastic medium with constant shearmodulus (the Hill body) is established. Time-discretization problemsfor generalized Newtonian fluidsare discussed, the unique solvabilityof the initial-value problem for the inelastic homogeneous Boltzmannequation for hard spheres, with a diffusive term representing a randombackground acceleration is proved and some qualitative properties ofthe solution are studied.

Equation of state - In physics and thermodynamics, an equation of state is a constitutive equation describing the state of matter under a given set of physical conditions. It provides a mathematical relationship between two or more state functions associated with the matter, such as its temperature, pressure, volume, or internal energy.

Differential equation - In mathematics, a differential equation is an equation in which the derivatives of a function appear as variables. Differential equations have many applications in physics, chemistry, and engineering, and are widespread in mathematical models explaining biological, social, and economic phenomena.

Mathematical physics - Mathematical physics is the scientific discipline concerned with "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories"1.

Mathematical models in physics - Mathematical models are of great importance in physics. Physical theories are almost invariably expressed using mathematical models, and the mathematics involved is generally more complicated than in the other sciences.
