This paper investigates the optimal recovery of Sobolev spaces Wr1[-1,1],r ∈ N in the space L1[-1,1].They obtain the values of the sampling numbers of Wr1[-1,1
In the paper,the authors provide a new proof and derive some new elliptic type(Hamilton type)gradient estimates for fast diffusion equations on a complete nonco
In this paper,the authors derive the existence criteria and the formulae of the weighted Moore-Penrose inverse,the e-core inverse and the f-dual core inverse in
The Carleson measures for weighted Dirichlet spaces had been characterized by Girela and Peláez,who also characterized the boundedness of Volterra type operato
