Transactions of the American Mathematical Society, Vol. 263, No. 2 (Feb., 1981), pp. 493-500 (8 pages) Let $\Delta'$ be the class of all derivatives. The main goal of this paper is the investigation ...
Let's try a simple linear function: f ( x) = x + c, where c is a constant. So, f ( x) = x + c is a solution for any a and any ...
The authors study time-harmonic Maxwell's equations in the junction of two rectangular waveguides. They prove existence and uniqueness of the solution, except for a discrete set of values of the ...
