       abstract = "Since its introduction in the early part of the nineteenth century, the theory of
         complex variables has played a steadily increasing role in mathematics, and in scientific research.
         In some fields complex algebra is used to simplify the description of a physical system. The use of
         a complex impedance Z in network theory is an example of this. In other fields complex algebra seems
         to be a basic ingredient of the physical laws. In Wave Mechanics for example a probability density
         P(x,t) is related to the square modulus of a wave function ψ(x,t) which is itself complex,
         being obtained from a wave equation whose coefficients may be complex.In mathematical research
         itself, it is rare to find a topic which is naturally restricted to real variables, and in many
         topics the extension to complex variables results in a simpler theory. For example a polynomial of
         degree n has exactly n zeros in the field of complex numbers.",
