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

Nonnegative Moore–Penrose inverses of Gram operators
Linear Algebra and its Applications, 2007 The main purpose of this work is to generalize the characterization of nonnegativity of inverses of Gram matrices in two directions: from finite dimensional real Euclidean spaces to (possibly) infinite dimensional real Hilbert spaces and from classical inverses to Moore-Penrose inverses.

The PCDID Approach to Treatment Effects Estimation: A Further Investigation
Journal of Applied Econometrics, EarlyView.ABSTRACT In the present paper, we study the so‐called “PCDID” approach to treatment effects estimation in panels with interactive effects where the factors represent trends whose effect need not be parallel across the cross‐sectional units. Our interest in this step‐wise approach originates with the observation that the interactive effects are ignored ...

Moore–Penrose inverse in rings with involution
Linear Algebra and its Applications, 2007 Let \(R\) be a ring with involution. An element \(a\in R\) is called regular if there exists an element \(b\in R\) such that \(a=aba\). A regular element \(a \in R\) is called Moore-Penrose invertible if there is an element \(a^\dag \in R\) such that \(aa^\dag a=a\), \(a^\dag aa^\dag=a^\dag\), \((aa^\dag)^*=aa^\dag\) and \((a^\dag a)^*=a^\dag a\).
