摘要：

The exact quantum S-matrices and conserved charges are known for affine Toda field theories(ATFTs). In this note we report on a new type of bi-linear sum rules of conserved quantities derived from these exact S matrices. They exist when there is a multiplicative identity among S-matrices of a particular ATFT. Our results are valid for simply laced as well as non-simply laced ATFTs. We also present a few explicit examples. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
