Some multivalued problems - Yosida approximation












0












$begingroup$


I study multi-valued problems on the basis of M. Chipot's book and I have a seemingly simple problem.
Set for a.e. $x in Omega$, $lambda > 0$, $forall t in mathbb{R}$:



$$ J_lambda (x,t) = (I +
lambda beta(x,cdot))^{-1}(t) $$



$$ beta_lambda (x,t) = (t-J_lambda(x,t))/lambda .$$



So $J_lambda$ is resolvent and $beta_lambda$ is Yosida approximation of $beta(x,t)$. Then there is said that it is easy to show that



$$ lambda_1 geq lambda_2 Longrightarrow beta_{lambda_1}(t) leq beta_{lambda_2}(t) $$
and for positive constant $c>0$:
$$ (c beta)_lambda = cbeta_{c lambda}.$$



I can't see it and and maybe some of you will be able to help?



Thanks in advance!
