Analytic and Polynomial Materials

چکیده

The theory of inhomogeneous analytic and polynomial materials is developed. These are media where the coefficients entering the equations involve analytic functions or polynomials. Three types of analytic or polynomial materials are identified. The first two types involve an integer p. If p takes its maximum value then we have a complete analytic or polynomial material. Otherwise it is incomplete analytic or polynomial material of rank p. For two-dimensional materials further progress can be made in the identification of analytic and polynomial materials by using the well-known fact that a 90◦ rotation applied to a divergence free field in a simply connected domain yields a curl-free field, and this can then be expressed as the gradient of a potential. Other exact results for the fields in inhomogeneous media are reviewed. Also reviewed is the subject of metamaterials, as these materials provide a way of realizing desirable coefficients in the equations.

Analytic Families of Semihyperbolic Generalized Polynomial-like Mappings

We show that the Hausdorff dimension of Julia sets in any analytic family of semihyperbolic generalized polynomial-like mappings (GPL) depends in a real-analytic manner on the parameter. For the proof we introduce abstract weakly regular analytic families of conformal graph directed Markov systems. We show that the Hausdorff dimension of limit sets in such families is real-analytic, and we asso...

A New Basis for Discrete Analytic Polynomials

A new basis {irk(z)}t.o for discrete analytic polynomials is presented for which the series 2k-o ak7Tk(z) converges absolutely to a discrete analytic function in the upper right quarter lattice whenever lim | ak \" k = 0. Introduction Let Z be the group of integers and consider functions / : Z X Z ^ C such that (1.1) f(x, y) + if(x + 1, y) / (* + 1, y + 1) if(x, y + 1) = 0 for every (x, y ) £ Z...
