On Kapteyn-Kummer Series' Integral Form [PDF]
, 2016 In this short research note we obtain double definite integral expressions for the Kapteyn type series built by Kummer's $M$ (or confluent hypergeometric ${}_1F_1$) functions.

The Wave Function of the Universe by the New Euclidean Path-integral Approach in Quantum Cosmology [PDF]
, 1992 The wave function of the universe is evaluated by using the Euclidean path integral approach. As is well known, the real Euclidean path integral diverges because the Einstein-Hilbert action is not positive definite.

A Note on Some Definite Integrals of Arthur Erdélyi and George Watson
Mathematics, 2021 This manuscript concerns two definite integrals that could be connected to the Bose-Einstein and the Fermi-Dirac functions in the integrands, separately, with numerators slightly modified with a difference in two expressions that contain the Fourier ...

On interacting fermions and bosons with definite total momentum [PDF]
, 2004 Any {\it exact} eigenstate with a definite momentum of a many-body Hamiltonian can be written as an integral over a {\it symmetry-broken} function $\Phi$.

Definite Integrals using Orthogonality and Integral Transforms
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We obtain definite integrals for products of associated Legendre functions with Bessel functions, associated Legendre functions, and Chebyshev polynomials of the first kind using orthogonality and integral transforms.

On the Henstock-Kurzweil Integral for Riesz-space-valued Functions on Time Scales
, 2017 We introduce and investigate the Henstock-Kurzweil (HK) integral for Riesz-space-valued functions on time scales. Some basic properties of the HK delta integral for Riesz-space-valued functions are proved.
