Extremal solution and Liouville theorem for anisotropic elliptic equations
Yuan Li
We study the quasilinear Dirichlet boundary problem \begin{equation}\nonumber \left\{ \begin{aligned} -Qu&=λe^{u} \quad \mbox{in}\quadΩ\\ u&=0 \quad \mbox{on}\quad\partialΩ,\\ \end…
The minus order for idempotents
Yuan Li, Jiajia Niu, Xiaoming Xu
Let and be idempotents on a Hilbert space The minus order is defined by the equation In this note, we first present some necessary an…
The structures and decompositions of symmetries involving idempotents
Yuan Li, Jiaxin Zhang, Nana Wei
Let be a separable Hilbert space and be an idempotent on We denote by and $…
The minimal and maximal symmetries for -contractive projections
Yuan Li, Xiaomei Cai, Jiajia Niu +1
In this paper, we firstly character the structures of symmetries such that a projection is -contractive. Then the minimal and maximal elements of the symmetries with…
The absolute values and support projections for a class of operator matrices involving idempotents
Yuan Li, Xiaomei Cai, Shuaijie Wang
Let and be a linear bounded operator from a Hilbert space into another Hilbert space In this paper, we conside…
Represent MOD function by low degree polynomial with unbounded one-sided error
Chris Beck, Yuan Li
In this paper, we prove tight lower bounds on the smallest degree of a nonzero polynomial in the ideal generated by or in the polynomial ring $F_p[x_1, \ldots,…
Von Neumann entropy and majorization
Yuan Li, Paul Busch
We consider the properties of the Shannon entropy for two probability distributions which stand in the relationship of majorization. Then we give a generalization of a theorem due…
