Modulus support functionals, Rajchman measures and peak functions
Revista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas ( IF 2.9 ) Pub Date : 2021-01-09 , DOI: 10.1007/s13398-020-00974-5

In 2000 Victor Lomonosov suggested a counterexample to the complex version of the Bishop–Phelps theorem on modulus support functionals. We discuss the \(c_0\)-analog of that example and demonstrate that the set of sup-attaining functionals is non-trivial, thus answering an open question, asked in Kadets et al. (The mathematical legacy of Victor Lomonosov. Operator theory. Advances in analysis and geometry 2. De Gruyter, Berlin, 157–187, 2020).

模量支持功能,拉奇曼测度和峰值功能

2000年,Victor Lomonosov提出了关于模版支持函数的Bishop–Phelps定理的复杂版本的反例。我们讨论该示例的\(c_0 \)-模拟,并证明具有最高功能的功能集很重要,因此回答了Kadets等人提出的一个开放性问题。(Victor Lomonosov的数学遗产。算子理论。分析和几何学的进展。2。De Gruyter,柏林,157-187,2020年)。
