The Bargmann type reduction for some Lax integrable two-dimensional generalization of the relativistic Toda lattice

Karpatsʹkì Matematičnì Publìkacìï, 2015
The possibility of applying the method of reducing upon finite-dimensional invariant subspaces, generated by the eigenvalues of the associated spectral problem, to some two-dimensional generalization of the relativistic Toda lattice with the triple ...

Analytically invariant and bi-invariant subspaces [PDF]

Transactions of the American Mathematical Society, 1972
The purpose of this paper is to call attention to some interesting weakly closed algebras related to a bounded linear operator T T acting on a Banach space X \mathfrak {X} and their associated lattices of invariant subspaces, namely, the algebras generated by the polynomials and by the rational functions ...

Intermittency in relation with 1/f noise and stochastic differential equations

, 2013
One of the models of intermittency is on-off intermittency, arising due to time-dependent forcing of a bifurcation parameter through a bifurcation point.

Searching for Subspace Trails and Truncated Differentials

IACR Transactions on Symmetric Cryptology, 2018
Grassi et al. [Gra+16] introduced subspace trail cryptanalysis as a generalization of invariant subspaces and used it to give the first five round distinguisher for Aes.

Permutation-invariant qudit codes from polynomials

, 2017
A permutation-invariant quantum code on $N$ qudits is any subspace stabilized by the matrix representation of the symmetric group $S_N$ as permutation matrices that permute the underlying $N$ subsystems.

The Lie h-Invariant Conformal Field Theories and the Lie h-Invariant Graphs

, 1991
We use the Virasoro master equation to study the space of Lie h-invariant conformal field theories, which includes the standard rational conformal field theories as a small subspace.

Conditional Lie-Bäcklund Symmetries and Reductions of the Nonlinear Diffusion Equations with Source

Abstract and Applied Analysis, 2014
Conditional Lie-Bäcklund symmetry approach is used to study the invariant subspace of the nonlinear diffusion equations with source ut=e−qx(epxP(u)uxm)x+Q(x,u), m≠1.

Projections on invariant subspaces [PDF]

Proceedings of the American Mathematical Society, 1962
and the arguments x are understood to be real numbers modulo 27. It is clear that H' is a closed subspace of Ll. D. J. Newman has shown quite recently [3] that there exist no bounded projections of L' onto H1. (By a projection we mean a linear operator P such that P2= P.) Certain facts about H' suggest a rather general setting for this type of theorem.

Recursive Forward-Backward EDMD: Guaranteed Algebraic Search for Koopman Invariant Subspaces

IEEE Access
The implementation of the Koopman operator on digital computers often relies on the approximation of its action on finite-dimensional function spaces. This approximation is generally done by orthogonally projecting on the subspace.
