3-filiform Lie algebras of dimension 8
(L'université Blaise Pascal, 1999)We give, up to isomorphism and in dimension 8, all the 3-filiform Lie algebras (whose Goze’s invariant is (n - 3,1,1,1))..

A census of critical sets based on non-trivial autotopisms of Latin squares of order up to five
(AIMS Press, 2020)This paper delves into the study of critical sets of Latin squares having a given isotopism in their autotopism group. ...

A class of nilpotent lie algebras
(Taylor and Francis, 2000)A p-filiform Lie algebra g is a nilpotent Lie algebra for which Goze’s invariant is (n–p,1,…,1). These Lie algebras are ...
