On -dimensional cycles and the vanishing of simplicial homology
In this paper we introduce the notion of a -dimensional cycle which is a
homological generalization of the idea of a graph cycle to higher dimensions.
We examine both the combinatorial and homological properties of this structure
and use these results to describe the relationship between the combinatorial
structure of a simplicial complex and its simplicial homology. In particular,
we show that over any field of characteristic 2 the existence of non-zero
-dimensional homology corresponds exactly to the presence of a
-dimensional cycle in the simplicial complex. We also show that
-dimensional cycles which are orientable give rise to non-zero simplicical
homology over any field.Comment: Substantially revised and expande
A new derivation of Hermite's integral for the Hurwitz zeta function
We obtain another proof of Hermite's integral for the Hurwitz zeta function
A Ramanujan enigma involving the first Stieltjes constant
We provide a rigorous formulation of Entry 17(v) in Ramanujan's Notebooks and
show how this relates to the first Stieltjes constant.
A new proposition 4.5 is included to show the close relationship with some
analysis presented by Candelpergher in 2017
Some possible approaches to the Riemann Hypothesis via the Li/Keiper constants
In this paper we consider some possible approaches to the proof of the
Riemann Hypothesis using the Li criterion
A formula connecting the Bernoulli numbers with the Stieltjes constants
We show that the formula recently derived by Coffey for the Stieltjes
constants in terms of the Bernoulli numbers is mathematically equivalent to the
much earlier representation derived by Briggs and Chowla
Euler-Hurwitz series and non-linear Euler sums
In this paper we derive two expressions for the Hurwitz zeta function
involving the complete Bell polynomials in the restricted case where q is a
positive integer greater than 1. The arguments of the complete Bell polynomials
comprise the generalised harmonic number functions. These in turn give rise to
Euler-Hurwitz series which may then be used to determine identities for
combinations of both linear and non-linear Euler sums
A summation by Gencev
Gencev has recently reported a closed form summation for an infinite series
involving the harmonic numbers and the central binomial numbers. This note
indicates a possible approach to the proof involving the dilogarithm function.Comment: Contains typographical correction
On the generalized Bernoulli numbers
We derive an expression for the generalized Bernoulli numbers in terms of the
Bernoulli numbers involving the (exponential) complete Bell polynomials
Elementary evaluations of some Euler sums
This short note contains elementary evaluations of some Euler sums
Determination of the Stieltjes constants at rational arguments
The Stieltjes constants have attracted considerable attention in recent years
and a number of authors, including the present one, have considered various
ways in which these constants may be evaluated. The primary purpose of this
paper is to belatedly highlight the fact that Deninger actually ascertained the
first generalised Stieltjes constant at rational arguments as long ago as 1984
and that all of the higher constants (at rational arguments) were determined in
principle by Chakraborty, Kanemitsu and Kuzumaki in 2009. Equivalent results
were obtained by Musser in his 2011 thesis.
The authors of the above papers simply referred to the constants as the
Laurent coefficients which explains why various electronic searches conducted
by this author for Stieltjes constants did not readily highlight these
particular sources.
In this paper the author has employed a slightly different argument to obtain
a simpler expression for the results originally derived by Chakraborty et al.
in 2009.Comment: Sign errors corrected in (6.6) and (6.9
