Gd. Pang et Bh. Zhao, CONSERVATION-LAWS OF THE QUANTIZED DAVEY-STEWARTSON-I SYSTEM IN (2+1)DIMENSIONS (VOL 34, PG 1063, 1993), Journal of mathematical physics, 34(11), 1993, pp. 5407-5408
The main formulas of the previous article are rewritten in a new and s
imple form. From the new form, the relation between the conservation l
aws of the quantized Davey-Stewartson I (DSI) system in (2 + 1) dimens
ions and that of the related systems in (1 + 1) dimensions can be very
clearly seen. References and notations are the same.
