    "abstract": "We present a new method for computation of the Korteweg-de Vries hierarchy\nvia heat invariants of the 1-dimensional Schrodinger operator. As a result new\nexplicit formulas for the KdV hierarchy are obtained. Our method is based on an\nasymptotic expansion of resolvent kernels of elliptic operators due to S.Agmon\nand Y.Kannai.",
