On the Existence of Zeros of Lyapunov-Monotone Operators
(University of Texas at Arlington, 1975-02)
**Please note that the full text is embargoed** ABSTRACT: Consider a nonlinear operator T from a Banach space into itself.
The study of the existence of zeros of T plays an important role in yielding fixed points of ...
