Differential inclusions with stable subinclusions. (English) Zbl 0816.34011
Using a refinement of Filippov’s theorem for differential inclusions, a singular perturbation problem ${x_ 1' \choose \varepsilon x_ 2'} \in F(x_ 1, x_ 2,t)$ for a set-valued map $$F : \mathbb{R}^{n_ 1} \times \mathbb{R}^{n_ 2} \times [0,T] \rightsquigarrow \mathbb{R}^{n_ 1} \times \mathbb{R}^{n_ 2}$$ is treated in this paper. Denoting by $$X^ \varepsilon : (0, \varepsilon_ 0) \rightsquigarrow C^{n_ 1} [0,T] \times L_ 2^{n_ 2} [0,T]$$ the solution map for a fixed initial condition, the lower semicontinuity of this map at 0 is proved.
