1 day ago · The automorphism α is called the main involution or grade involution. Elements that are pure in this Z 2-grading are simply said to be even or odd. Remark. The Clifford algebra is not a Z-graded algebra, but is Z-filtered, where Cl ≤i (V, Q) is the subspace spanned by all products of at most i elements of V.

2 days ago · As expected, an involution on a semihypergroup is analogous to inverses on a semigroup. Hence a semihypergroup with an identity and an involution of the following characteristic is a hypergroup. Definition 3 (Hypergroup) A semihypergroup \((H, *)\) is called a hypergroup if it satisfies the following conditions: (A5):

4 days ago · This paper investigates two involutions on binary trees. One is the mirror symmetry of binary trees which combined with the classical bijection φ between binary trees and plane trees answers an open problem posed by Bai and Chen. This involution can be generalized to weakly increasing trees, which admits to merge two recent equidistributions ...
