Determining conductivity by boundary measurements

Robert Kohn, Michael Vogelius

Research output: Contribution to journalArticlepeer-review


In [2], A. P. Caldéron posed the following question: can one determine the heat conductivity of an object from static temperature and heat flux measurements at the boundary? We show that such measurements uniquely determine the conductivity and all of its derivatives at the boundary.
