Inclus？es dinamicas em escalas temporais: existência de solu？？es sob a hipótese de semicontinuidade inferior

in this paper we consider the problem of differential inclusion in time scales whose vector field is a multifunction, that is, a function that maps points to sets. it is provided conditions of existence without requiring compactness of the vector field; it is required that the vector field is closed, convex, and lower semicontinuous. in previous work in literature, it is required that the field is either scalar or compact, convex, and has closed graph.
