Transplants of Nevanlinna theory to some fields of research

R. Nevanlinna’s theory describes the value distribution of meromorphic functions in the plane. We have successfully transplanted it to a theory describing the value distribution of piecewise linear and continuous functions on the real line in the max-plus algebra. As an application, we can find some results on piecewise linear continuous solutions which correspond to those on meromorphic solutions to complex differential equations. Especially, some growth formulas for an ultra-discretized entire function are obtained in terms of the coefficients of its tropical series expansion.
