Coherence and uniqueness theorems for averaging processes in statistical mechanics
Michiel Hazewinkel, Hugo H Torriani
Let S be the set of scalings 1, 2,3,4, ... and consider the corresponding set of scaled lattices in the plane. In this paper averaging operators are defined for plaquette functions…
Word Hopf algebras
Michiel Hazewinkel
Two important generalizations of the Hopf algebra of symmetric functions are the Hopf algebra of noncommutative symmetric functions and its graded dual the Hopf algebra of quasisym…
Symmetric functions, noncommutative symmetric functions, and quasisymmetric functions II
Michiel Hazewinkel
Like its precursor this paper is concerned with the Hopf algebra of noncommutative symmetric functions and its graded dual, the Hopf algebra of quasisymmetric functions. It complem…
Symmetric functions, noncommutative symmetric functions, and quasisymmetric functions
Michiel Hazewinkel
This paper is concerned with two generalizations of the Hopf algebra of symmetric functions that have more or less recently appeared. The Hopf algebra of noncommutative symmetric f…
Mathematical knowledge management is needed
Michiel Hazewinkel
In this lecture I discuss some aspects of MKM, Mathematical Knowledge Management, with particuar emphasis on information storage and information retrieval.
Explicit polynomial generators for the ring of quasi-symmetric functions over the integers
Michiel Hazewinkel
In [5, 6] it has been proved that the ring of quasisymmetric functions over the integers is free polynomial, see also [4]. This is a matter that has been of great interest since 19…
