Abstract:Let $B$ be a real Banach space partially ordered by a closed convex cone $P$ with nonempty interior $overset{circ}P$. We study the continuation method for the monotone operator $A:, overset{circ}P rightarrow overset{circ}P$ which satisfies

begin{eqnarraystar}A(tx) geq t^{alpha (a,b)}, A(x), end{eqnarraystar}



for all $x in overset{circ}P$, $t in [a,, b] subset (0,, 1)$, where $alpha (a,b) in (0,, 1)$. Thompson's metric is among the main tools we are using.
Keywords:$alpha$-sublinear   cone   fixed point   generalized contraction   monotone operator   ordered Banach space   Thompson's metric
