Algebraic and analytic Dirac induction for graded affine Hecke algebras

open access: yes, 2013
We define the algebraic Dirac induction map $\Ind_D$ for graded affine Hecke algebras. The map $\Ind_D$ is a Hecke algebra analog of the explicit realization of the Baum-Connes assembly map in the $K$-theory of the reduced $C^*$-algebra of a real ...

Algebras with cycle-finite Galois coverings [PDF]

open access: yesTransactions of the American Mathematical Society, 2011
It is proved that every finite-dimensional algebra over an algebraically closed field which admits a cycle-finite Galois covering with torsion-free Galois group is tame, and a description of the indecomposable finite-dimensional modules over these algebras is given.

Efficient Dynamics: Reduced‐Order Modeling of the Time‐Dependent Schrödinger Equation

open access: yesAdvanced Physics Research, EarlyView.
Reduced‐order modeling (ROM) approaches for the time‐dependent Schrödinger equation are investigated, highlighting their ability to simulate quantum dynamics efficiently. Proper Orthogonal Decomposition, Dynamic Mode Decomposition, and Reduced Basis Methods are compared across canonical systems and extended to higher dimensions.

Remedies for Misapplications of Sylvester’s Criterion: A Pedagogic Illustration

open access: yesSpreadsheets in Education, 2021
Sylvester’s criterion, which verifies the positive definiteness of any real symmetric matrix by examining the signs of all leading principal minors, is an excellent analytical tool.

A Non-commutative Real Nullstellensatz Corresponds to a Non-commutative Real Ideal; Algorithms

open access: yes, 2012
This article takes up the challenge of extending the classical Real Nullstellensatz of Dubois and Risler to left ideals in a *-algebra A. After introducing the notions of non-commutative zero sets and real ideals, we develop three themes related to our ...

On the Calkin algebra and the covering homotopy property [PDF]

open access: yesTransactions of the American Mathematical Society, 1975
Let H \mathcal {H} be a separable Hilbert space, B ( H ) \mathcal {B}(\mathcal {H}) the bounded operators on H , K \mathcal {H},\mathcal {K} the ideal of compact ...

Risk‐aware safe reinforcement learning for control of stochastic linear systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

AN APPROACH TO ALLEVIATE THE FALSE ALARM IN BUILDING CHANGE DETECTION FROM URBAN VHR IMAGE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Building change detection from very-high-resolution (VHR) urban remote sensing image frequently encounter the challenge of serious false alarm caused by different illumination or viewing angles in bi-temporal images.

Ideal codes over separable ring extensions [PDF]

open access: yes, 2014
This paper investigates the application of the theoretical algebraic notion of a separable ring extension, in the realm of cyclic convolutional codes or, more generally, ideal codes.
