Están mal las derivadas segundas. La derivada del producto de dos funciones es igual al producto de la derivada de la primera por la segunda sin derivar más el producto de la primera sin derivar por la derivada de la segunda.
La derivada segunda respecto de x dos veces es:



y así con el resto.
Otra acalaración: cuando piden calcular el Hessiano, creo que piden calcular la forma cuadrática Hessiano, y no su matriz asociada.
Haciendo las correcciones sobre las derivadas igual se llega a la conclusión de que g(0,1) es un extremo local.

Saludos!
