Determinants and Compositions of Natural Numbers [PDF]
arXiv, 2010 We consider a particular type of matrices which belong at the same time to the class of Hessenberg and Toeplitz matrices, and whose determinants are equal to the number of a type of compositions of natural numbers. We prove a formula in which the number of weak compositions with a fixed number of zeroes is expressed in terms of the number of ...

Several generalizations on Wolstenholme Theorem [PDF]
MATEC Web of Conferences, 2022 This paper generalizes Wolstenholme theorem on two aspects. The first generalization is a parameterized form: let p > k + 2, k ≥ 1, ∀t ∈ ℤ, then ${{(pt + p - 1)!} \over {(pt)!}}\mathop \sum \limits_{m = 0}^{k - 1} {( - 1)^m}\mathop \sum \limits_{1 \le {

On approximation numbers of composition operators [PDF]
Journal of Approximation Theory, 2012 We show that the approximation numbers of a compact composition operator on the weighted Bergman spaces $\mathfrak{B}_ $ of the unit disk can tend to 0 arbitrarily slowly, but that they never tend quickly to 0: they grow at least exponentially, and this speed of convergence is only obtained for symbols which do not approach the unit circle.
