A Determinant Expression for the Generalized Bessel Polynomials [PDF]
Journal of Applied Mathematics, 2013 Using the exponential Riordan arrays, we show that a variation of the generalized Bessel polynomial sequence is of Sheffer type, and we obtain a determinant formula for the generalized Bessel polynomials. As a result, the Bessel polynomial is represented

MathematicsIn this paper, we introduce and study the Tricomi continuants, a family of tridiagonal determinants forming a Sheffer sequence closely related to the Tricomi polynomials and the Laguerre polynomials.

Identities on Changhee Polynomials Arising from λ ‐Sheffer Sequences [PDF]
Complexity, 2022 In this paper, authors found a new and interesting identity between Changhee polynomials and some degenerate polynomials such as degenerate Bernoulli polynomials of the first and second kind, degenerate Euler polynomials, degenerate Daehee polynomials, degenerate Bell polynomials, degenerate Lah–Bell polynomials, and degenerate ...

On an approximation operator and its Lipschitz constant [PDF]
Journal of Numerical Analysis and Approximation Theory, 2002 In this note we consider an approximation operator of Kantorovich type in which expression appears a basic sequence for a delta operator and a Sheffer sequence for the same delta operator.

Generalized Sheffer sequences satisfying piecewise functional conditions [PDF]
, 2001 The well-known relationship between linear functionals and Sheffer sequences is extended to the case of piecewise functional conditions, where one functional determines the beginning, and a second functional shapes the remainder of a the sequence.

Combinatorial identities involving the central coefficients of a Sheffer matrix [PDF]
, 2019 Given m ∈ N, m ≥ 1, and a Sheffer matrix S = [s_{n,k}]_{n,k}≥0, we obtain the exponential generating series for the coefficients binomial(a+(m+1)n,a+mn)^{−1}*s_{a+(m+1)n,a+mn}.

On the zeros of certain Sheffer sequences and their cognate sequences
, 2023 Given a Sheffer sequence of polynomials, we introduce the notion of an associated sequence called the cognate sequence. We study the relationship between the zeros of this pair of associated sequences and show that in case of an Appell sequence, as well as a more general family of Sheffer sequences, the zeros of the members of each sequence (for large ...

The zero locus and some combinatorial properties of certain exponential Sheffer sequences [PDF]
, 2022 We present combinatorial and analytical results concerning a Sheffer sequence with an exponential generating function of the form $G(s,z)=e^{czs+\alpha z^{2}+\beta z^{4}}$, where $\alpha, \beta, c \in \mathbb{R}$ with ...

Practical Hex-Mesh optimization via edge-cone rectification [PDF]
, 2015 The usability of hexahedral meshes depends on the degree to which the shape of their elements deviates from a perfect cube; a single concave, or inverted element makes a mesh unusable.
