Query: Comments on non-commuting variables, n-ary algebras, and first-order
  differential equations   Use of certain non-commuting variables is considered in first-order
differential equations. Superspace variables are discussed within the setting
of first-order ordinary differential equations and n-ary algebras. Results on
quadratic systems based on non-associative algebras are presented. A system
related to a Li\'enard system associated to an Abel's differential equation of
the second kind is given as an example.
