No. of bitstreams: 0 Previous issue date: 2021-01-01; This chapter presents the study of the stability theory for generalized ordinary differential equations (ODEs). The results on the stability of the trivial solution in the framework of the generalized ODE are inspired in the theory, developed by Aleksandr M. Lyapunov on the stability of solutions for cl...

No. of bitstreams: 0 Previous issue date: 2021-01-01; This chapter presents the concepts of uniform boundedness, quasiuniform boundedness, and uniform ultimate boundedness in the scenery of generalized ordinary differential equations (ODEs). It includes criteria of uniform boundedness and uniform ultimate boundedness for the generalized ODE. The chapter pr...
Financiadora de Estudos e Projetos; We study degenerate parabolic systems arised in three-phase capillary flows in porous media under a pressure control at the inflow and outflow boundaries. We perform a mathematical study of such systems for a class of linear capillarity pressure functions. To this end, a theory of nondegenerate parabolic approximations is developed. It has been proved the unique solvability o...
