Lie Symmetry Reductions and Exact Solutions to the Rosenau Equation
The Lie symmetry analysis is performed on the Rosenau equation which arises in modeling many physical phenomena. The similarity reductions and exact solutions are presented. Then the exact analytic solutions are considered by the power series method.

Symmetries of the Robinson-Trautman equation [PDF]
We study point symmetries of the Robinson--Trautman equation. The cases of one- and two-dimensional algebras of infinitesimal symmetries are discussed in detail. The corresponding symmetry reductions of the equation are given.

Adaptive Symmetry Reduction [PDF]
Symmetry reduction is a technique to counter state explosion for systems of regular structure. It relies on idealistic assumptions about indistinguishable components, which in practice may only be similar. In this paper we present a generalized algebraic approach to symmetry reduction for exploring a structure without any prior knowledge about its ...

Symmetry reduction for stochastic hybrid systems [PDF]
This paper is focused on adapting symmetry reduction, a technique that is highly successful in traditional model checking, to stochastic hybrid systems. To that end, we first show that performability analysis of stochastic hybrid systems can be reduced to a stochastic reachability analysis (SRA).

The algebraic and Hamiltonian structure of the dispersionless Benney and Toda hierarchies [PDF]
The algebraic and Hamiltonian structures of the multicomponent dispersionless Benney and Toda hierarchies are studied. This is achieved by using a modified set of variables for which there is a symmetry between the basic fields.

AbstractSymmetry reduction is an effective state-space reduction technique for model checking, and works by restricting search to equivalence class representatives with respect to a group of symmetries for a model. A major problem with symmetry reduction techniques is the time taken to compute the representative of a state, which can be prohibitive. In

On a negative flow of the AKNS hierarchy and its relation to a two-component Camassa-Holm equation [PDF]
Different gauge copies of the Ablowitz-Kaup-Newell-Segur (AKNS) model labeled by an angle $\theta$ are constructed and then reduced to the two-component Camassa--Holm model.

Point symmetries of generalized Toda field theories: II. Symmetry reduction [PDF]
Summary: The Lie symmetries of a large class of generalized Toda field theories are studied and used to perform symmetry reduction. Reductions lead to generalized Toda lattices, on one hand, and to periodic systems, on the other. Boundary conditions are introduced to reduce theories on an infinite lattice to those on semi-infinite or finite ones.
