Abstract.
Let E be a pre-ordered real Banach space and f:[0,T)×E→E a quasimontone increasing function. We prove one-sided estimates of the form ∂+q[y−x,f(t,y)−f(t,x)]≤α(t,q(y−x)) with respect to seminorms q generated by a single positive linear functional. Such estimates lead to growth conditions, for example for the total variation of the solution of u′=f(t,u) in function spaces.
