On p-height orthogonality and characterization of inner product spaces
收藏 引用
JOURNAL OF MATHEMATICAL ANALYSIS AND APPLICATIONS 2025年 第2期543卷
作者: Heidarirad, Somaye Jahanipur, Ruhollah Dehghani, Mahdi Univ Kashan Fac Math Sci Dept Pure Math Kashan Iran
In this paper, we introduce and study the concept of p-height orthogonality in real normed linear spaces. This orthogonality generalizes the well-known Singer and height orthogonalities. First, we investigate main pro... 详细信息

Density of compactly supported smooth functions CC(Rd) in Musielak-Orlicz-Sobolev spaces W1,Φ(Ω)
收藏 引用
JOURNAL OF FUNCTIONAL ANALYSIS 2025年 第1期288卷
作者: Kaminska, Anna Zyluk, Mariusz Univ Memphis Dept Math Sci Memphis TN 38152 USA
We investigate here the density of the set of the restrictions from C-C(infinity)(R-d) to C-C(infinity)(Omega) in the Musielak-Orlicz-Sobolev space W-1,W-Phi(Omega). It is a continuation of article [15], where we have... 详细信息

The Schrodinger equation with cubic nonlinearities on the half-line in low regularity spaces
收藏 引用
JOURNAL OF MATHEMATICAL ANALYSIS AND APPLICATIONS 2024年 第1期537卷
作者: Himonas, A. Alexandrou Yan, Fangchi Univ Notre Dame Dept Math Notre Dame IN 46556 USA Virginia Polytech Inst & State Univ Dept Math Blacksburg VA 24061 USA
The initial-boundary value problem for the Schrodinger equation with cubic nonlinearities of the form u(3-k)u(k) is studied on the half-line. Using the Fokas solution formula for the corresponding linear forced proble... 详细信息

JOURNAL OF FUNCTIONAL ANALYSIS 2024年 第2期287卷
作者: Gaebler, Harrison Sari, Bunyamin Univ North Texas Dept Math 1155 Union Circle 311430 Denton TX 76203 USA
A Banach space is said to have the Lebesgue property if every Riemann-integrable function f : [0 , 1] -> X is Lebesgue almost everywhere continuous. We give a characterization of the Lebesgue property in terms of a... 详细信息
