| Summary:
|
The paper is a mathematical background of the paper of D. Mayer, B. Ulrych where the mathematical model of the skin effect is established and discussed. It is assumed that the currents passing through parallel conductors are under effect of a variable magnetic field. The phasors of the density of the current are solutions of $f(x)-jq \sum{^k_{i=1}}b_i \int_{Si} f(y) V(|y-x|)dy-c_p=h(x)$ for $x\in S_p, p=1,\dots,k$, $\int_{Si}f(x)dx=I_i, i=1,\dots, k$, where $j$ is the imaginary unit, $b_i,q,I_i$ are given constants, #h(x)$ is a given function and $f(x)$ is an unknown function and $c_i$ are unknown constants. The first and the second section of this paper are devoted to the problem of existence and unicity of a solution. The third section is devoted to a numerical method. (English) |
