 I will discuss quadratic estimates for operators of the form DB where 
  
D is a first order system and B is a multiplication operator. The 
  
mathematics is an extension of ideas that have evolved in 
  
consideration of Calderón’s question on the boundedness of Cauchy 
  
integrals on Lipschitz curves, and Kato’s question on square roots of 
  
elliptic operators. The applications include not only these theorems, 
  
but also results on the perturbation of Hodge-Dirac operators on 
  
Riemannian manifolds, and on the solvability of elliptic boundary 
  
value problems with square integrable boundary data. The latest work 
  
is joint with Andreas Axelsson and Pascal Auscher.
