Abstract: We prove uniqueness of a discontinuous principal coefficient of a second-order parabolic equation of the form a_0+χ(Q^*)b with known smooth a_0 and unknown b=b(x) from all possible lateral boundary measurements of solutions of this equation. In the proofs, we make use of singular solutions of parabolic equations
