Some remarks about the monotone inclusion for solutions of nonlinear equations by regula-falsi-like methods [PDF]

open access: yes, 1983
summary:First, a result of J. W. Schmidt about the monotone enclosure of solutions of nonlinear equations is generalized. Then an iteration method is considered, which is more effective than other known methods.

Nonlinear Dirac Equations, Monotonicity Formulas and Liouville Theorems [PDF]

open access: yesCommunications in Mathematical Physics, 2019
Abstract We study the qualitative behavior of nonlinear Dirac equations arising in quantum field theory on complete Riemannian manifolds. In particular, we derive monotonicity formulas and Liouville theorems for solutions of these equations. Finally, we extend our analysis to Dirac-harmonic maps with curvature term.

The Solutions of Mixed Monotone Fredholm-Type Integral Equations in Banach Spaces

open access: yesDiscrete Dynamics in Nature and Society, 2013
By introducing new definitions of ϕ convex and -φ concave quasioperator and v0 quasilower and u0 quasiupper, by means of the monotone iterative techniques without any compactness conditions, we obtain the iterative unique solution of nonlinear mixed ...
