Quantum mechanics in the K-field formalism: Field equation

The paper considers a field equation for representing a microparticle as an extended object constructed from that field (K field). It is shown that in contrast to the equation of an S field (i.e., Schrödinger equation), the boundary-value problem for the K-field equation cannot be used for a unique determination of the parameters of a microparticle in steady states. An auxiliary equation, therefore, is necessary to ensure that the solution of the K -field equation is unique. This is in complete agreement with the physical meaning of K field.
