Gian-Carlo Rota He worked on the theory of incidence algebras (which generalize the 19th-century theory of Möbius inversion) and popularized their study among combinatorialists, set the umbral calculus on a rigorous foundation, unified the theory of Sheffer sequences and polynomial sequences of binomial type, and worked on fundamental problems in probability theory.

Seminar Themes

dates	led by	subjects
March 2010	A. K. Kwasniewski	Subject 8 GHW algebra again leitmotiv: : Graves –Heisenberg –Weyl (GHW) algebra - apart from differential and dual graded posets that bring together combinatorics, representation theory, topology, geometry and many more specific branches of mathematics and mathematical physics – seems to reappear now in a presumed connection: GHW algebra representation <-> Pascal-like triangles, which come up in pairs : “direct ” and “inverted” Pascal-like triangles. (Inversion formulas?) A specific family of examples is delivered by “duality triads” and their Pascal-like triangles. Fibonaciego ; Pascala; q-Gaussa; Stirlinga I; Stirlinga II; Pascal fractals; New_triangles; Fibonacci et Pascal; Pascal_Fibonacci
February 2010	A. K. Kwasniewski	Subject 7 Lucas people are (p,q)-mumber people leitmotiv: If Édouard Lucas had been used a=p and b= q notation, he would be perhaps recognized as the Grand Father of all "(p,q) - people"
December 2009	A. K. Kwasniewski	Subject 6 On compositions of numbers and graphs leitmotiv: The main purpose is to pose a couple of problems which are easily formulated thought some seem to be not yet solved. These problems are of general interest for discrete mathematics including a new twig of a bough of theory of graphs i.e. a given graph compositions.
August, September 2009	M. Dziemianczuk A.K.Kwasniewski	Subject 5 Generalizations of Fibonomial Coefficients leitmotiv: to what extent one may make basic properties of F-nomials survive while extending the notion of binomials, incidence coefficients, Whitney numbers..etc...?
June, July 2009	A.K.Kwasniewski	Subject 4 natural join versus ordinal sum leitmotiv: Natural join construction of graded posets
April, May 2009	M. Dziemianczuki	Subject 3 tiling, boxes, etc leitmotiv: Is the problem of KoDAGs tiling solvable?
Feb, March 2009	A.K.Kwasniewski	Subject 2 upside down notation leitmotiv: Is the upside down notation efficiency - an indication? of a structure to be named?
Dec 2008 Jan 2009	A.K.Kwasniewski	Subject 1 oDAGs & KoDAGs in Company leitmotiv: oDAGs stem from where and whence?
