Multiview subspace clustering via low‐rank correlation analysis
IET Computer Vision, EarlyView., 2022 The framework of our proposed method. The unifying graph S is adaptively used to capture the low–rank correlation between samples in different views. S also represents the clustering structure with a rank constraint to avoid its spectral post–processing.

Analytic Families of Self-Adjoint Compact Operators Which Commute with Their Derivative
Communications in Advanced Mathematical Sciences, 2020 Spectral properties of analytic families of compact operators on a Hilbert space are studied. The results obtained are then used to establish that an analytic family of self-adjoint compact operators on a Hilbert space $\mathcal{H},$ which commute with ...

The rigged Hilbert space approach to the Lippmann-Schwinger equation. Part I
, 2006 We exemplify the way the rigged Hilbert space deals with the Lippmann-Schwinger equation by way of the spherical shell potential. We explicitly construct the Lippmann-Schwinger bras and kets along with their energy representation, their time evolution ...

Astronomische Nachrichten, EarlyView.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examined how Bitcoin, energy prices, and geopolitical risk interact by examining the first four moments (mean, variance, skewness, and kurtosis) of their return distributions by using wavelet analysis. The findings reveal that the co‐movement patterns of energy index, geopolitical risk index, and Bitcoin prices are time and ...

Advances in Mathematical Physics, 2014 A new algorithm called multistep reproducing kernel Hilbert space method is represented to solve nonlinear oscillator’s models. The proposed scheme is a modification of the reproducing kernel Hilbert space method, which will increase the intervals of ...

Communications on Pure and Applied Mathematics, EarlyView.Abstract We consider a planar Coulomb gas ensemble of size N$N$ with the inverse temperature β=2$\beta =2$ and external potential Q(z)=|z|2−2clog|z−a|$Q(z)=|z|^2-2c \log |z-a|$, where c>0$c>0$ and a∈C$a \in \mathbb {C}$. Equivalently, this model can be realised as N$N$ eigenvalues of the complex Ginibre matrix of size (c+1)N×(c+1)N$(c+1) N \times (c+1)

Communications in Mathematical Physics, 2000 The basic mathematical framework for super Hilbert spaces over a Grassmann algebra with a Grassmann number-valued inner product is formulated. Super Hilbert spaces over infinitely generated Grassmann algebras arise in the functional Schroedinger representation of spinor quantum field theory in a natural way.

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Cognitive‐behavioral therapy (CBT) is the most well‐established treatment for binge‐eating disorder (BED), but the mechanisms of change remain poorly understood. This study investigated in CBT for BED the effects of overvaluation of shape and weight and dietary restraint on subsequent objective binge‐eating episodes (OBEs). Method In
