作者：吴文标楼森岳 School of Physical Science and Technology Ningbo UniversityNingbo315211China Shanghai Key Laboratory of Trustworthy Computing East China Normal UniversityShanghai200062China

An Alice-Bob Kadomtsev-Petviashivili(ABKP) equation with shifted-parity(■_s^x parity with a shift for the space variable x) and delayed time reversal(■d, time reversal with a delay) symmetries is investigated. The multi-soliton solutions with three arbitrary even or odd functions are found from the ■_s^x■_d symmetry reductions of a coupled local KP system. The result shows that for the ABKP equation with ■_s^x■_d nonlocality, the odd numbers of solitons are *** solitons of the ABKP must be paired. For the ABKPⅡ equation, there exists a critical value of wave numbers for the existence of paired solitons. For the ABKPI equation, there are two types of 'breather' excitations. A lump solution of the ABKPI may possess four, five or six leaves.

Painlevé property, local and nonlocal symmetries, and symmetry reductions for a (2+1)-dimensional integrable KdV equation

引用

Chinese Physics B 2021年第1期30卷 178-184页

作者：王晓波贾曼楼森岳 School of Physical Science and Technology Ningbo UniversityNingbo 315211China

The Painlevé property for a(2+1)-dimensional Korteweg–de Vries(KdV) extension, the combined KP3(Kadomtsev–Petviashvili) and KP4(cKP3-4), is proved by using Kruskal’s simplification. The truncated Painlevé expansion is used to find the Schwartz form, the Bäcklund/Levi transformations, and the residual nonlocal symmetry. The residual symmetry is localized to find its finite Bäcklund transformation. The local point symmetries of the model constitute a centerless Kac–Moody–Virasoro algebra. The local point symmetries are used to find the related group-invariant reductions including a new Lax integrable model with a fourth-order spectral problem. The finite transformation theorem or the Lie point symmetry group is obtained by using a direct method.
