A generalisation of the summation formula of Plana [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1999
An extension of the classical summation formula of Plana is obtained. The extension is obtained by using the zeros of a Bessel function of the first kind.

Dualizing the Poisson summation formula.

open access: yesProceedings of the National Academy of Sciences, 1991
If f(x) and g(x) are a Fourier cosine transform pair, then the Poisson summation formula can be written as 2sumfrominfinityn = 1g(n) + g(0) = 2sumfrominfinityn = 1f(n) + f(0). The concepts of linear transformation theory lead to the following dual of this classical relation. Let phi(x) and gamma(x) = phi(1/x)/x have absolutely convergent integrals over

A dimensionally continued Poisson summation formula

open access: yes, 2011
We generalize the standard Poisson summation formula for lattices so that it operates on the level of theta series, allowing us to introduce noninteger dimension parameters (using the dimensionally continued Fourier transform).

Partial Sums of Two Quartic q-Series

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
The partial sums of two quartic basic hypergeometric series are investigated by means of the modified Abel lemma on summation by parts. Several summation and transformation formulae are consequently established.

A New Old Babylonian Date List with Hammurapi Year Names

open access: yesDirāsāt fī al-tārīẖ wa-al-āṯār, 2023
This paper contains the publication of a previously unknown date list of Hammurapi, the king of Babylon, with his year formulae, kept in the Sulaymaniyah Museum in Iraq. The tablet originally contained the year formulae for 42 years of Hammurapi's reign

Certain families of differential equations associated with the generalized 1-parameter Hermite–Frobenius Euler polynomials

open access: yesMathematical and Computer Modelling of Dynamical Systems
This study introduces a new approach to the development of generalized 1-parameter, 2-variable Hermite–Frobenius–Euler polynomials, which are characterized by their generating functions, series definitions and summation formulae.

Further Closed Formulae of Exotic 3F2-Series

open access: yesAxioms, 2023
By making use of the linearization method, we examine a class of nonterminating 3F2-series with five free integer parameters that yields twenty summation formulae.

A simple proof of Bailey's very-well-poised 6-psi-6 summation

open access: yes, 2000
We give elementary derivations of some classical summation formulae for bilateral (basic) hypergeometric series. In particular, we apply Gauss' 2-F-1 summation and elementary series manipulations to give a simple proof of Dougall's 2-H-2 summation ...

Why does the sign problem occur in evaluating the overlap of HFB wave functions?

open access: yesPhysics Letters B, 2018
For the overlap matrix element between Hartree–Fock–Bogoliubov states, there are two analytically different formulae: one with the square root of the determinant (the Onishi formula) and the other with the Pfaffian (Robledo's Pfaffian formula).

Closed-form evaluation of 2D static lattice sums

open access: yes, 2016
In the present paper, employing properties of the complete elliptic integrals of the first and second kind, we deduce closed-form formulae for the lattice sums and other new formulae.
