Shapіro, Мichael Mathematical Analysis 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. John Wiley & Sons 2013 Article PeerReviewed text uk http://eprints.zu.edu.ua/13298/1/2013-mma.Solution_PDE.pdf Pogoruі, А.
