全部非负矩阵学习基础Though total positivity appears in various branches of mathematics, it is rather unfamiliar even to linear algebraists, when compared with positivity. With some unified methods we present a concise survey on totally positive matrices and r
The purpose of this note is to prove uniqueness of the positive radial solution to the Dirichlet problem for 2u& u+ u3=0, (1.1) on the annulus 0= [x # R3 : R1 <| x|< R2] where 0< R1 < R2 ; (the Dirichlet condition at R 2= is interpreted,
We study the uniqueness of positive radial solutions to the Dirichlet boundary value problem for the semilinear elliptic equation u + f( | x | , u) = 0 in a finite ball or annulus in R n, n 3. Applying our main results to the cases when f is indepen
Existence of Three Positive Solutions for Weighted p-Laplacian Boundary Value Problemson Infinite Intervals，Song Huijuan ，Yin Jingxue ，This paper is concerned with the existence of multiple positive solutions for(ω(t)ψp(u'(t)))'+h(t)f(t,u(t),u'(t))=o
The positive influences of Mg2+, Mn2+and Zn2+ addition on the gamma-CGTase Production by Bucillus macorous，王峰，堵国成，The effects of Mg2+, Mn2+ or Zn2+ addition on gamma-CGTase production by Bacillus macorous WSH02-06 were studied. The gamma-CGTase yield
Relative perturbation bounds for generalized nonnegative and positive polar factors，李寒宇，Hu Yang，The changes in the generalized nonnegative and positive polar factors of weighted polar decomposition are studied under the additive perturbation. Some re
Necessary and Sufficient Conditions for Positive and Negative Solutions of BSDEs with Continuous Coefficients，徐玉红，，As we know that, in stochastic finance, each pricing mechanism corresponds to a well-defined BSDE. The behaviors of g exert an influenc
Positive fractional derivative equation modeling of non-Fourier heat conduction，孙逸飞，，This letter makes the first attempt to develop differential equation model of non-Fourier heat conductions by using positive time-fractional derivative. Numerical co
