Abstract
This paper deals with the initial value problem of the type
where t is the time, L is a linear first order operator (matrix-type) in Quaternionic Analysis and \({\varphi}\) is a regular function taking values in the Quaternionic Algebra. The article proves necessary and sufficient conditions on the coefficients of operator L under which L is associated to the Cauchy-Fueter operator of Quarternionic Analysis.
This criterion makes it possible to construct the operator L for which the initial problem (1), (2) is solvable for an arbitrary initial regular function \({\varphi}\) and the solution is also regular for each t.
