| 中文摘要: |
| 首先讨论了约束离散KP 可积方程族一种等价形式: 差分算子的商. 接下来, 利用这种新的描述形式,
构造了约束离散KP方程族的完全Virasoro对称. |
| 英文摘要: |
| In this paper, an alternative formulation of the constrained discrete KP hierarchy
as a ratio of difference operators is discussed. Then by using this new formation, the full Virasoro
symmetry for the constrained discrete KP hierarchy is constructed. |
