Natural join construction of graded posets versus ordinal sum and discrete hyper boxes

A. K. Kwasniewski

One introduces here the natural join $P \os Q$ of graded posets and with correspondingly maximal and minimal sets being identical as expressed by ordi…

Cobweb posets as noncommutative prefabs

A. K. Kwasniewski

A class of new type graded infinite posets with minimal element are considered. These so called cobweb posets introduced recently by the present author provide a wide range of new…

Extended finite operator calculus as an example of algebraization of analysis

A. K. Kwasniewski, E. Borak

A wardian calculus of sequences started almost seventy years ago constitutes the general scheme for extensions of the classical umbral operator calculus considered by many afterwar…

The logarithmic fibbinomial formula

A. K. Kwasniewski

Roman logarithmic binomial formula analogue has been found . It is presented here also for the case of fibonomial coefficients which recently have been given a combinatorial interp…

Fibonomial cumulative connection constants

A. K. Kwasniewski

In this note we present examples of cumulative connection constants included new fibonomial ones. All examples posses combinatorial interpretation.

Fibonacci q-gaussian sequences

A. K. Kwasniewski

The summation formula within pascalian triangle resulting in the fibonacci sequence is extended to the -binomial coefficients -gaussian triangles.
