In this paper, a new integrable two-component system, mt=[m(uxvx-uv+uvx-uxv)]x,nt=[n(uxvx - uv + uvx - uxv)]x, where m = u - uxx and n=v-vxx, is proposed. Our system is a generalized version of the integrable system mt=[m(ux2-u2)]x, which was shown having cusped solution (cuspon) and W/M-shape soliton solutions by Qiao [J. Math. Phys. 47, 112701 (2006). The new system is proven integrable not only in the sense of Lax-pair but also in the sense of geometry, namely, it describes pseudospherical surfaces. Accordingly, infinitely many conservation laws are derived through recursion relations. Furthermore, exact solutions such as cuspons and W/M-shape solitons are also obtained. [ABSTRACT FROM AUTHOR]
