is said to be tame if

of
. A two-dimensional 0-associative
algebra is tame, but a four-dimensional 4-associative
algebra and a three-dimensional 1-associative algebra
need not be tame. It is conjectured that a three-dimensional 2-associative
algebra is tame, and proven that a three-dimensional 3-associative
algebra is tame if it possesses a multiplicative identity
element.
