Gleason parts for algebras of holomorphic functions on the ball of $\mathbf{c_0}$

Richard M. Aron, Verónica Dimant, Silvia Lassalle, Manuel Maestre

摘要:

对于具有开单位球的复Banach空间$X$,考虑$B_X.$上有界标值全纯函数的Banach代数$\mathcal H^\infty(B_X)$和一致连续函数的子代数$\mathcal A_u(B_X)$,用$\mathcal A,$表示任一代数,研究$\mathcal A.$上标值同态集$X = c_0.$的Gleason部分。

英文摘要:

For a complex Banach space $X$ with open unit ball $B_X,$ consider the Banach algebras $\mathcal H^\infty(B_X)$ of bounded scalar-valued holomorphic functions and the subalgebra $\mathcal A_u(B_X)$ of uniformly continuous functions on $B_X.$ Denoting either algebra by $\mathcal A,$ we study the Gleason parts of the set of scalar-valued homomorphisms $\mathcal M(\mathcal A)$ on $\mathcal A.$ Following remarks on the general situation, we focus on the case $X = c_0.$
