Sheffer operation in ortholattices
No full textsummary:We introduce the concept of Sheffer operation in ortholattices and, more generally, in lattices with antitone involution. By using this, all the fundamental operations of an ortholattice or a lattice with antitone involution are term functions built up from the Sheffer operation. We list axioms characterizing the Sheffer operation in these lattices
Sheffer and Non-Sheffer Polynomial Families
No full textBy using the integral transform method, we introduce some non-Sheffer polynomial sets. Furthermore, we show how to compute the connection coefficients for particular expressions of Appell polynomials

Recurrence relations for the Sheffer sequences
No full textAbstractIn this paper, using the production matrix of an exponential Riordan array [g(t),f(t)], we give a recurrence relation for the Sheffer sequence for the ordered pair (g(t),f(t)). We also develop a new determinant representation for the general term of the Sheffer sequence. As applications, determinant expressions for some classical Sheffer polynomial sequences are derived

Multivariate Expansion Associated with Sheffer-type Polynomials and Operators
No full textWith the aid of multivariate Sheffer-type polynomials and differential operators, this paper provides two kinds of general expansion formulas, called respectively the first expansion formula and the second expansion formula, that yield a constructive solution to the problem of the expansion of A(ˆt)f([g(t)) (a composition of any given formal power series) and the expansion of the multivariate entire functions in terms of multivariate Sheffer-type polynomials, which may be considered an application of the first expansion formula and the Sheffer-type operators. The results are applicable to combinatorics and special function theory
The zero locus and some combinatorial properties of certain exponential Sheffer sequences
No full textWe present combinatorial and analytical results concerning a Sheffer sequence
with an exponential generating function of the form , where with and
. We demonstrate that the zeros of all polynomials in such a Sheffer
sequence are either real, or purely imaginary. Additionally, using the
properties of Riordan matrices we show that our Sheffer sequence satisfies a
three-term recurrence relation of order 4, and we also exhibit a connection
between the coefficients of these Sheffer polynomials and the number of nodes
with a a given label in certain marked generating trees
BI-G-STARLIKE FUNCTION ASSOCIATED WITH NORMALIZED ONE VARIABLE GEGENBAUER AND BELL-SHEFFER POLYNOMIALS INVOLVING GREGORY COEFFICIENTS
No full textIn this enquiry, applying normalized one variable Gegenbauer and Bell-Sheffer Polynomials, the authors introduce a new class of bi-G-starlike functions defined by Gregory and Caratheodory coefficients. Coefficient bounds for the new class were obtained and were consequently used to investigate the concept of Fekete-Szego functional and Toeplitz determinant in this direction
Analysis of the readout of a high rate MWPC
No full textAn analytical method to reduce the raw data supplied by a high-speed multiwire proportional chamber (MWPC) is presented. The results obtained with the MWPC and the associated readout system, LeCroy PCOS III, when monitoring a high-intensity flux of positive pions delivered by the M11 channel at TRIUMF are discussed. The method allows the flux intensity, the beam envelope and the detector efficiency to be determined with little uncertainty (few %) at intense particle beams ( > 107 particles/s)
