An alternative proof of an inequality by Zhu

, 2020
In this short note, we provide a new and relatively simple proof of an inequality established by Zhu in 2009. The main tools employed are Lazarevic inequality and the arithmetic-geometric mean inequality.

Strictly positive definite kernels on the $2$-sphere: beyond radial symmetry

, 2020
The paper introduces a new characterisation of strict positive definiteness for kernels on the 2-sphere without assuming the kernel to be radially (isotropic) or axially symmetric. The results use the series expansion of the kernel in spherical harmonics.

Further Results on the Logarithmic Integral

Sarajevo Journal of Mathematics
The logaritmic integral li$( x^r)$ and its associated functions li$ _+ ( x^r)$ and li$_-(x^r)$ are defined as locally summable functions on the real line and their derivatives are found as distributions.

Some Commutative Neutrix Convolutions Involving the Fresnel Integrals

Sarajevo Journal of Mathematics
The Fresnel cosine integral C$(x)$, the Fresnel sine integral S$(x)$ and the associated functions $C_+(x)$, $C_-(x)$, $S_+(x)$ and $S_-(x)$ are defined as locally summable functions on the real line. Some convolutions and commutative neutrix convolutions
