A Baer Lie ring is a Lie ring L satisfying the following two conditions:

  1. L is a nilpotent Lie ring and has nilpotency class at most two. In other words, L/Z(L) is an abelian Lie ring, where Z(L) is the center of L.
  2. The additive group of L is powered over the prime 2. In other words, L is uniquely 2-divisible, i.e., for every a \in L, there is a unique element b \in L such that 2b = a, where 2b means b + b.

A Baer Lie ring is a Lie ring that can participate as the Lie ring side of a Baer correspondence.
