Rota-Baxter operators on the polynomial algebras, integration and averaging operators
No full textThe concept of a Rota–Baxter operator is an algebraic abstraction of integration. Following this classical connection, we study the relationship between Rota–Baxter operators and integrals in the case of the polynomial algebra k[x]
k[x]
. We consider two classes of Rota–Baxter operators, monomial ones and injective ones. For the first class, we apply averaging operators to determine monomial Rota–Baxter operators. For the second class, we make use of the double product on Rota–Baxter algebras
Yang-Baxter maps and the discrete KP hierarchy
No full textWe present a systematic construction of the discrete KP hierarchy in terms of Sato–Wilson-type shift operators. Reductions of the equations in this hierarchy to 1+1-dimensional integrable lattice systems are considered, and the problems that arise with regard to the symmetry algebra underlying the reduced systems as well as the ultradiscretizability of these systems are discussed. A scheme for constructing ultradiscretizable reductions that give rise to Yang–Baxter maps is explained in two explicit examples

Pattern avoidance in partial permutations
No full textMotivated by the concept of partial words, we introduce an analogous concept of partial permutations. A partial permutation of length n with k holes is a sequence of symbols in which each of the symbols from the set {1,2,...,n-k} appears exactly once, while the remaining k symbols of are "holes". We introduce pattern-avoidance in partial permutations and prove that most of the previous results on Wilf equivalence of permutation patterns can be extended to partial permutations with an arbitrary number of holes. We also show that Baxter permutations of a given length k correspond to a Wilf-type equivalence class with respect to partial permutations with (k-2) holes. Lastly, we enumerate the partial permutations of length n with k holes avoiding a given pattern of length at most four, for each n >= k >= 1
Iain Baxter : Landscape Works
No full textCatalogue to accompany Baxter’s exhibition of approximately 40 multidisciplinary landscape works (1965-1999) in painting, photography, printmaking, video and sculpture. Tupper’s foreword draws attention to the artist’s connections with Alberta and its landscape. The author also refers to the role of landscape in Baxter’s art as a “container for the social and the self.” The artist’s statement describes the various uses of landscape in his studies and work since the late 1950s. In her biographical essay, curator Townsend analyses Baxter’s artistic contribution over four decades, giving special attention to landscape and the impact of the N. E. Thing Company (founded with Ingrid Baxter in 1966) on the genre’s renewal. Bibliography 1p. 4 bibl. ref
