Similarity:

The purpose of this paper is to study some properties related to convexity order and coefficients estimation for a general integral operator. We find the convexity order for this operator, using the analytic functions from the class of starlike functions of order $α$ and from the class $𝒞𝒱ℋ (β)$ and also we estimate the first two coefficients for functions obtained by this operator applied on the class $𝒞𝒱ℋ (β)$ .

The sizes of the classes of $H^{(N)}$ -sets

Václav Vlasák (2014)

Fundamenta Mathematicae

Similarity:

The class of $H^{(N)}$ -sets forms an important subclass of the class of sets of uniqueness for trigonometric series. We investigate the size of this class which is reflected by the family of measures (called polar) annihilating all sets from the class. The main aim of this paper is to answer in the negative a question stated by Lyons, whether the polars of the classes of $H^{(N)}$ -sets are the same for all N ∈ ℕ. To prove our result we also present a new description of $H^{(N)}$ -sets.

$(m, r)$ -central Riordan arrays and their applications

For integers $m > r \geq 0$ , Brietzke (2008) defined the $(m, r)$ -central coefficients of an infinite lower triangular matrix $G = (d, h) = {(d_{n, k})}_{n, k \in ℕ}$ as $d_{m n + r, (m - 1) n + r}$ , with $n = 0, 1, 2, \dots$ , and the $(m, r)$ -central coefficient triangle of $G$ as $G^{(m, r)} = {(d_{m n + r, (m - 1) n + k + r})}_{n, k \in ℕ} .$ It is known that the $(m, r)$ -central coefficient triangles of any Riordan array are also Riordan arrays. In this paper, for a Riordan array $G = (d, h)$ with $h (0) = 0$ and $d (0), h^{'} (0) \neq 0$ , we obtain the generating function of its $(m, r)$ -central coefficients and give an explicit representation for the $(m, r)$ -central Riordan array $G^{(m, r)}$ in terms of the Riordan array $G$ ....

Nonanalyticity of solutions to $\partial_{t} u = \partial ²_{x} u + u ²$

Grzegorz Łysik (2003)

Colloquium Mathematicae

Similarity:

It is proved that the solution to the initial value problem $\partial_{t} u = \partial ²_{x} u + u ²$ , u(0,x) = 1/(1+x²), does not belong to the Gevrey class $G^{s}$ in time for 0 ≤ s < 1. The proof is based on an estimation of a double sum of products of binomial coefficients.

Similarity:

Let J ⊂ ℝ² be the set of couples (x,q) with q > 1 such that x has at least one representation of the form $x = \sum_{i = 1}^{\infty} c_{i} q^{- i}$ with integer coefficients $c_{i}$ satisfying $0 \leq c_{i} < q$ , i ≥ 1. In this case we say that $(c_{i}) = c ₁ c ₂ . . .$ is an expansion of x in base q. Let U be the set of couples (x,q) ∈ J such that x has exactly one expansion in base q. In this paper we deduce some topological and combinatorial properties of the set U. We characterize the closure of U, and we determine its Hausdorff dimension. For (x,q) ∈ J, we also...

Generalizations of Milne’s $U (n + 1)$ $q$ -Chu-Vandermonde summation

Jian-Ping Fang (2016)

Czechoslovak Mathematical Journal

Similarity:

We derive two identities for multiple basic hyper-geometric series associated with the unitary $U (n + 1)$ group. In order to get the two identities, we first present two known $q$ -exponential operator identities which were established in our earlier paper. From the two identities and combining them with the two $U (n + 1)$ $q$ -Chu-Vandermonde summations established by Milne, we arrive at our results. Using the identities obtained in this paper, we give two interesting identities involving binomial...

The number of conjugacy classes of elements of the Cremona group of some given finite order

Jérémy Blanc (2007)

Bulletin de la Société Mathématique de France

Similarity:

This note presents the study of the conjugacy classes of elements of some given finite order $n$ in the Cremona group of the plane. In particular, it is shown that the number of conjugacy classes is infinite if $n$ is even, $n = 3$ or $n = 5$ , and that it is equal to $3$ (respectively $9$ ) if $n = 9$ (respectively if $n = 15$ ) and to $1$ for all remaining odd orders. Some precise representative elements of the classes are given.
