摘要：On the basis of the characteristic polynomials of Lax matrixes for the Belov-Chaltikian lattice hierarchy, we introduce the corresponding trigonal curve. We study the calculation of genus of the algebraic curve, its properties at infinity, and the construction of three kinds of Abel differentials. We establish the corresponding Baker-Akhiezer functions and meromorphic functions. The straightening out of various soliton flows is exactly given through the Abel map and Abel-Jacobi coordinates. Using the theory of algebraic curves, we obtain algebro-geometric solutions of the Belov-Chaltikian lattice hierarchy.
