Invariant Subspace and Classification of Soliton Solutions of the Coupled Nonlinear Fokas-Liu System

Frontiers in Physics, 2019
In this work, the coupled nonlinear Fokas-Liu system which is a special type of KdV equation is studied using the invariant subspace method (ISM). The method determines an invariant subspace and construct the exact solutions of the nonlinear partial ...

Person Re-identification by Local Maximal Occurrence Representation and Metric Learning [PDF]

, 2015
Person re-identification is an important technique towards automatic search of a person's presence in a surveillance video. Two fundamental problems are critical for person re-identification, feature representation and metric learning.

Algorithms for entanglement renormalization [PDF]

, 2009
We describe an iterative method to optimize the multi-scale entanglement renormalization ansatz (MERA) for the low-energy subspace of local Hamiltonians on a D-dimensional lattice.

A decoupling approach to the quantum capacity [PDF]

, 2007
We give a short proof that the coherent information is an achievable rate for the transmission of quantum information through a noisy quantum channel. Our method is to produce random codes by performing a unitarily covariant projective measurement on a ...

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 ...

On the relaxed maximum-likelihood blind MIMO channel estimation for orthogonal space-time block codes

, 2020
This paper concerns the maximum-likelihood channel estimation for MIMO systems with orthogonal space-time block codes when the finite alphabet constraint of the signal constellation is relaxed.

Integral geometry of complex space forms [PDF]

, 2013
We show how Alesker's theory of valuations on manifolds gives rise to an algebraic picture of the integral geometry of any Riemannian isotropic space.

Noise Characterization: Keeping Reduction Based Per-turbed Quantum Walk Search Optimal

EPJ Web of Conferences, 2019
In a recent work by Novo et al. (Sci. Rep. 5, 13304, 2015), the invariant subspace method was applied to the study of continuous-time quantum walk (CTQW).

Exact Solutions to the Fractional Differential Equations with Mixed Partial Derivatives

Axioms, 2018
In this paper, the solvability of nonlinear fractional partial differential equations (FPDEs) with mixed partial derivatives is considered. The invariant subspace method is generalized and is then used to derive exact solutions to the nonlinear FPDEs ...

2D-DOA Estimation for EMVS Array with Nonuniform Noise

International Journal of Antennas and Propagation, 2021
Electromagnetic vector sensor (EMVS) array is one of the most potential arrays for future wireless communications and radars because it is capable of providing two-dimensional (2D) direction-of-arrival (DOA) estimation as well as polarization angles of ...
