Finite Blaschke Products and Decomposition [PDF]
Journal of Mathematics and Applications, 2019 Let $B(z)$ be a finite Blaschke product of degree $n$. We consider the problem when a finite Blaschke product can be written as a composition of two nontrivial Blaschke products of lower degree related to the condition $% B\circ M=B$ where $M$ is a Möbius transformation from the unit disk onto itself.

Finite products of regularized products [PDF]
Mathematical Research Letters, 2008 The product $\big(\p a_m\big)\cdot\big(\p b_m\big)$ of two regularized products is not in general equal to the regularized product $\p (a_m\cdot b_m)$. We consider the discrepancy $F$, defined by $$ \exp(F ):=\frac{\p (a_m\cdot b_m)}{\big(\p a_m\big)\cdot\big(\p b_m\big)}. $$ When the terms $a_m$ and $b_m$ depend on parameters, we show in certain cases

On Products of Subgroups of Finite Groups
Mediterranean Journal of Mathematics, 2022 AbstractWe give sufficient conditions to ensure that the intersection of the product of two subgroups A and B of a group G with an abelian normal subgroup K of G is a subgroup of G.

Extended Wang sum and associated products.
PLoS ONE, 2022 The Wang sum involving the exponential sums of Lerch's Zeta functions is extended to the finite sum of the Huwitz-Lerch Zeta function to derive sums and products involving cosine and tangent trigonometric functions.

Infinite symmetric products of rational algebras and spaces
Comptes Rendus. Mathématique, 2022 We show that the infinite symmetric product of a connected graded-commutative algebra over $\mathbb{Q}$ is naturally isomorphic to the free graded-commutative algebra on the positive degree subspace of the original algebra.

Sums of finite products of Genocchi functions
Advances in Difference Equations, 2017 In a previous work, it was shown that Faber-Pandharipande-Zagier and Miki’s identities can be derived from a polynomial identity which in turn follows from a Fourier series expansion of sums of products of Bernoulli functions.

Unbiased Estimates for Products of Moments and Cumulants for Finite Populations
Mathematics, 2023 Let FN be the distribution function of a finite real population of size N. Let Fn be the empirical distribution function of a sample of size n drawn from the population without replacement.

⁎-freeness in finite tensor products
Advances in Applied Mathematics, 2017 In this paper, we consider the following question and variants thereof: given $\mathbf D:=\big(a_{1;i}\otimes\cdots\otimes a_{K;i}:i\in I\big)$, a collection of elementary tensor non-commutative random variables in the tensor product of probability spaces $(\mathcal A_1\otimes\cdots\otimes\mathcal A_K,ϕ_1\otimes\cdots\otimesϕ_K)$, when is $\mathbf D$ $*
