Notice that the Taylor-Hood element satisfied the inf-sup condition Brezzi, 1991 and again, by Brezzis theorem, the unique solvability of the variational formulation 6 was obtained.
Nótese que el elemento Taylor-Hood satisface la condición inf-sup Brezzi, 1991 y nuevamente por el teorema de Brezzi es inmediata la existencia de una única solución para 6. Teorema 2.
