Explicit invariant solutions for invariant linear differential operators

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1984
SynopsisLet F be a real analytic function on a real analytic manifold X. Let P be a linear differential operator on X such that , where Q is an ordinary differential operator with analytic coefficients whose singular points are all regular. For each (isolated) critical value z of F, we construct locally an F-invariant solution u of the equation Pu - v,

Group invariant solutions to a centro-affine invariant flow

Archiv der Mathematik, 2017
The authors systematically study the group-invariant solutions of the centroaffine heat flow using Lie's theory of symmetry groups.

Group-Invariant Solutions

1986
When one is confronted with a complicated system of partial differential equations arising from some physically important problem, the discovery of any explicit solutions whatsoever is of great interest. Explicit solutions can be used as models for physical experiments, as benchmarks for testing numerical methods, etc., and often reflect the asymptotic

Functionally invariant solutions to Maxwell’s system

Journal of Applied and Industrial Mathematics, 2017
Summary: We consider the problem of the existence of functionally invariant solutions to Maxwell's system. The solutions found contain functional arbitrariness, which is used for determining the parameters of Maxwell's system (the dielectric and magnetic constants).

Invariant Measures and Statistical Solutions

2016
In this chapter we prove the existence of invariant measures associated with two-dimensional autonomous Navier–Stokes equations. Then we introduce the notion of a stationary statistical solution and prove that every invariant measure is also such a solution.

Identifying invariant solutions with Nektar++

2022
Several canonical flows are known to remain stable for arbitrary high values of the Reynolds numbers. In the case of those flows transition to turbulence is the result of the onset of equilibrium states, populating the phase space, rather than a cycle of bifurcations that takes the flow away from its laminar form.

Replication invariance of bargaining solutions

International Journal of Game Theory, 1986
The author considers a bargaining problem, i.e. a problem of choosing a single output from the set S of possible outputs. An output is characterized by a sequence \(x_ 1,...,x_ n\) of utilities obtained by each of the n players. Without any loss of generality we can assume that a status quo point is \(x_ i=0\).
