text: # Strongly positive bilinear form
  
  A bilinear form, a(•,•) whose arguments are elements of normed vector space V is a strongly positive bilinear form if and only if there exists a constant, c>0, such that
  
      $a(u,u)\geq c\cdot \|u\|^{2}$
  
  for all $u\in V$ where $\|\cdot \|$ is the norm on V.
