An algebra is called finitary if it consists of finite-rank transformations of a vector space. We classify finitary simple and finitary irreducible Lie algebras over an algebraically closed field of characteristic = 2, 3.

✦ Synopsis
Let F be an algebraically closed field of characteristic = 2, 3, W a F -vector space and
The faithful irreducible L-modules are determined. It is shown that L has minimal ideals. If a minimal ideal S is infinite-dimensional then SW is a completely reducible L-module. Suppose L ∩ fgl(W ) = (0), W is L-irreducible and char(F ) > 3. Then L is classified in terms of L ∩ fgl(W ).
