## Complex Vector Functional EquationsThe subject of complex vector functional equations is a new area in the theory of functional equations. This monograph provides a systematic overview of the authors' recently obtained results concerning both linear and nonlinear complex vector functional equations, in all aspects of their utilization. It is intended for mathematicians, physicists and engineers who use functional equations in their investigations. Contents: Linear Complex Vector Functional Equations: General Classes of Cyclic Functional Equations; Functional Equations with Operations Between Arguments; Functional Equations with Constant Parameters; Functional Equations with Constant Coefficients; Systems of Linear Functional Equations; Nonlinear Complex Vector Functional Equations: Quadratic Functional Equations; Modified Quadratic Functional Equations; Expanded Quadratic Functional Equations; Higher Order Functional Equations; Systems of Nonlinear Functional Equations. Readership: Researchers, lecturers, senior undergraduates and graduate students dealing with functional equations. |
