Abstract: We introduce a renormalization procedure for the τfunction of integrable systems. We illustrate the procedure using the supercritical Toda shock problem as a model problem. We start with a finite chain and take the limit of the solution as the number of particles N → ∞. This results in a new formula for the τfunction for the problem with an infinite chain. We apply the renormalized formula to rederive leadingorder effects of the supercritical Toda shock problem. © 1998 John Wiley & Sons, Inc.
