Dear all,

I am trying to solve the system found in the attached pdf as a mixed system. I want to solve the same
problem as the one found here, but with the use of Schur complements and not linear algebra.

In a previous discussion about this problem, Lawrence mentioned that the test function for integral(lambda*Theta(x-Lp)dx) needs to be considered as coming from the real space of constant functions. Could you please elaborate on this?

Regards,

Anna.
