On classical inequalities of trigonometric and hyperbolic functions
Barkat Ali Bhayo, Jozsef Sandor
This article is the collection of the six research papers, recently written by the authors. In these papers authors refine the inequalities of trigonometric and hyperbolic function…
Trigonometric and Hyperbolic Inequalities
Jozsef Sandor
We prove various new trigonometric and hyperbolic inequalities of Jordan, Wilker, Huygens or Cusa-Huygens type. Connections with bivariate means, as well as monotonicity and convex…
A note on certain inequalities for bivariate means
Jozsef Sandor
We obtain simple proofs of certain inequalites for bivariate means.
On bi-unitary harmonic numbers
Jozsef Sandor
We introduce notions of bi-unitary, bi*-unitary and bi**-unitary harmonic numbers, along with their preliminary study.
Inequalities for multiplicative arithmetic functions
Jozsef Sandor
We study arithmetic inequalities for multiplicative, sub(super)-multiplicative, sub(super)-homogeneous functions. Applications for the classical arithmetic functions are pointed ou…
Extremal orders of compositions of certain arithmetical functions
József Sándor, László Tóth
We study the exact extremal orders of compositions of certain arithmetical functions, including the functions , , and , representing the sum…
