Low-rank matrix recovery problem is difficult due to its non-convex properties and it is usually solved using convex relaxation approaches. In this paper, we formulate the non-convex low-rank matrix recovery problem exactly using novel Ky Fan 2-k-norm-based models. A general difference of conv...
首先引入范数(norm)的定义。 2.1.1 定义(范数)Norm 在线性空间X上的一个范数实质上即是一个实值映射‖⋅‖:X→R,这个映射满足如下性质:对于∀x,y∈X,∀λ∈F,有 N1:‖x‖≥0,(映射的像正定) N2:‖x‖=0⟺x=0,(算子/映射的核仅有0元素) ...

Hamiltonian simulations of quantum systems require a finite-dimensional representation of the operators acting on the Hilbert space H. Here we give a prescription for gauge links and canonical momenta of an SU(2) gauge theory, such that the matrix representation of the former is diagonal in H. ...
