A Class of Fractions adding how Pupils wish

Martin Himmel

Motivated by children inventing creatively laws on how to add or multiply fractions, we introduce four fraction operations and discover some of their properties.

Cauchy Pairs

Martin Himmel

The notion of pairable functions is introduced and some of its properties are developed. In this connection the famous Euler identity is interpreted as a property of certain pairab…

Pendants to the Euler Beta function

Martin Himmel

Motivated by the integral representation of the Euler Beta function, we introduce its Cauchy siblings and investigate some of their properties. Two of these newly introduced functi…

The logarithmic Cauchy quotient mean

Martin Himmel, Janusz Matkowski

Motivated by recent results on beta-type functions, a new family of means, which are of logarithmic Cauchy quotient type, are determined and characterized.

Homogeneous Beta-type functions

Martin Himmel, Janusz Matkowski

All beta-type functions, which are p-homogeneous, are determined. Applying this result, we show that a beta-type function is a homogeneous mean iff it is the harmonic one. A reform…

Directional convexity and characterizations of Beta and Gamma functions

Martin Himmel, Janu sz Matkowski

The logarithmic convexity of restrictions of the Beta functions to rays parallel to the main diagonal and the functional equation \[ ϕ\left( x+1\right) =\frac{x\left( x+k\right) }{…
