The Slutsky equation (or Slutsky identity) in economics, named after Eugen Slutsky, relates changes in Marshallian (uncompensated) demand to changes in Hicksian (compensated) demand, which is known as such since it compensates to maintain a fixed level of utility.. By singularity with the price vector on its null space or singularity in p, we mean that pis a right eigenvector of the Slutsky matrix associated with a zero eigenvalue, since Walras' law (assumed throughout the paper) implies that pis a left eigenvector of the matrix.

Although strictly speaking the Slutsky equation only applies to infinitesimal changes in prices, it is standardly used a linear approximation for finite changes.
