Existence results for second-order dynamic inclusion with $m$-point boundary value conditions on time scales. (English)
[J] Appl. Math. Lett. 20, No. 8, 885-891 (2007). ISSN 0893-9659

The authors investigate the existence of solutions of the $m$-point boundary problem for the second-order dynamic inclusion on a time scale $\Bbb{T}$ $$ \aligned y^{\triangle\nabla}(t)\in F(y(t)),\qquad t\in[0,b]_{\Bbb{T}},\\ y^{\triangle}(0)=\sum_{i=1}^{m-2}a_{i}y^{\triangle}(\zeta_i), \quad y(b)=\sum_{i=1}^{m-2}b_{i}y(\zeta_i). \endaligned $$ They use a fixed point theorem of Sadovskii and a continuous selection theorem for lower semi-continuous multi-valued maps.
