Introduction Let (L;) be a loop, i.e., L is a set with a binary operation such that for all a; b 2 L the equations a x = b and y a = b have unique solutions x; y 2 L, and there exists an element 0 2â€¦ (More)

A K-loop or Bruck loop is a Bol loop with the automorphic inverse property. An overview of the most important theorems on K-loops and some of their relatives, especially Kikkawa loops, is given.â€¦ (More)
