Sci. %T Solutions for PDEs with constant coefficients and derivability of functions ranged in commutative algebras %X It is well known that the real and imaginary parts of any holomorphic function are harmonic functions of two variables. In this paper, we extend this idea to finite-dimensional commutative algebras; that is, we prove that if some basis of a subspace of a commutative algebra satisfies a polynomial equation, then the components of a monogenic function on the subspace are solutions of the respective partial differential equation (PDE). We illustrate these concepts with a few examples. %D 2013 %I John Wiley & Sons %L zu213298
