Title: Wronskian solutions of the two-dimensional Toda molecule equation, Part II Speaker: Junyi Tu Time: 9:30am‐10:30am Place: NES 104
Bi-directional Wronskian solutions and double Wronskian solutions are constructed for the two-dimensional Toda molecule equation. Two determinant identities including the Jacobi identity are the base of construction.
Title: Wronskian solutions and Grammian solutions to the two-dimensional Toda lattice equation, Part II Speaker: Magdy Gamil Asaad Time: 9:30am‐10:30am Place: NES 104
The Plücker relation and Pfaffian identities are applied to the two-dimensional Toda lattice equation. The resulting Wronskian and Pfaffian formulations generate two kinds of determinant solutions to the two-dimensional Toda lattice equation.
Title: \(W\)-algebras in CKP and BKP hierarchies Speaker: Jingsong He, Ningbo University Zhejiang, PR China Time: 4:00pm‐5:00pm Place: PHY 108
This talk aims to construct additional symmetries associated with the constrained CKP and BKP hierarchies, and further to give the action of the symmetry flows on the eigenfunction and adjoint eigenfunction. We further show that their acting on the space of the wave operator, \(\partial_k^*\) forms two centerless algebras \(W^{cC}_{1+\infty}\) and \(W^{cB}_{1+\infty}\)-subalgebra of centerless \(W_{1+\infty}\), respectively.

Title: Multi-wave solutions for nonlinear equations by the multiple exp-function method Speaker: Wen-Xiu Ma Time: 9:30am‐10:30am Place: NES 104
A multiple exp-function method is proposed for constructing multi-wave solutions of nonlinear partial differential equations. The method is oriented towards ease of use and capability of computer algebra systems, and provides a direct and systematical solution procedure. Using Maple, an application of the approach is made to the \(3+1\) dimensional potential-Yu-Toda-Sasa-Fukuyama equation, and so, exact \(1\)-wave, \(2\)-wave and \(3\)-wave solutions are generated, along with \(1\)-soliton, \(2\)-soliton and \(3\)-soliton type solutions.
Title: Wronski-type and Gramm-type Pfaffian solutions to the coupled KP equation, Part II Speaker: Alrazi Abdeljabbar Time: 9:30am‐10:30am Place: NES 104
Pfaffian techniques are used to present Pfaffian structure of the coupled KP equation. The resulting Pfaffian formulation yields two kinds of Pfaffian solutions to the coupled KP equation. Such a solution process leads to Pfaffianization of the KP equation.

Using Pfaffian techniques, we discuss the common structure of soliton equations and show how fundamental soliton equations, such as the KP, BKP, coupled KP, Toda lattice and Toda molecule equations, resolve themselves into Pfaffian identities.

We discuss a few fundamental Pfaffian identities in soliton theory. These include expansion formulae, addition formulae and derivative formulae for Pfaffians. The computation using Pfaffians is much simpler than using determinants in generating soliton solutions to Hirota bilinear equations.

Title: Determinant and pfaffian solutions of Hirota bilinear equations, Part III Speaker: Yaning Tang, Northwest Polytechnic University P.R. China Time: 9:30am‐10:30am Place: NES 104
We discuss some facts about determinants and Pfaffians, and explore determinant and Pfaffian solutions to Hirota bilinear equations. Laplace expansions of determinants and Jacobi identities for determinants will be used to present Plücker relations, perfect square formulae, addition formulae and derivative formulae for determinants and Pfaffians.
