Monomial codes seen as invariant subspaces
It is well known that cyclic codes are very useful because of their applications, since they are not computationally expensive and encoding can be easily implemented. The relationship between cyclic codes and invariant subspaces is also well known.

CP symmetry and symplectic modular invariance
We analyze CP symmetry in symplectic modular-invariant supersymmetric theories. We show that for genus $g\ge 3$ the definition of CP is unique, while two independent possibilities are allowed when $g\le 2$.

Cluster robust error estimates for the Rayleigh–Ritz approximation I: Estimates for invariant subspaces [PDF]
This is the first part of a paper that deals with error estimates for the Rayleigh–Ritz approximations to the spectrum and invariant subspaces of a bounded Hermitian operator in a Hilbert or Euclidean space.

Automated detection of symmetry-protected subspaces in quantum simulations
The analysis of symmetry in quantum systems is of utmost theoretical importance, useful in a variety of applications and experimental settings, and difficult to accomplish in general. Symmetries imply conservation laws, which partition Hilbert space into

Approximately Invariant Subspaces [PDF]
Invariant subspaces are well documented in the literature and approximations for them exist. Approximately invariant subspaces have properties that are highly desirable for iterative solution strategies of large sparse matrix systems and for ...

Maximal J-semi-definite invariant subspaces of unbounded J-selfadjoint operators in Krein spaces [PDF]
In this paper we establish conditions for the existence of maximal J-semi-definite invariant subspaces of unbounded J-selfadjoint operators. Our results allow for operators where all entries of the formal matrix representation induced by the indefinite ...

Certain invariant subspaces for operators with rich eigenvalues
For a connected open subset Ω of the plane and n a positive integer, let Bn(Ω) be the space introduced by Cowen and Douglas. In this article we study the spectrum of restrictions of T in order to obtain more information about the invariant subspaces of T.

New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design
This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...
