Spinelli, Ernesto
 Group Algebras with Minimal Strong Lie Derived Length Let \$KG\$ be a non-commutative strongly Lie solvable group algebra of a group \$G\$ over a field \$K\$ of positive characteristic \$p\$. In this note we state necessary and sufficient conditions so that the strong Lie derived length of \$KG\$ assumes its minimal value, namely \$\lceil \log_{2}(p+1)\rceil \$. Keywords:group algebras, strong Lie derived lengthCategories:16S34, 17B30

Ndogmo, J. C.
 Properties of the Invariants of Solvable Lie Algebras We generalize to a field of characteristic zero certain properties of the invariant functions of the coadjoint representation of solvable Lie algebras with abelian nilradicals, previously obtained over the base field \$\bbC\$ of complex numbers. In particular we determine their number and the restricted type of variables on which they depend. We also determine an upper bound on the maximal number of functionally independent invariants for certain families of solvable Lie algebras with arbitrary nilradicals. Categories:17B30, 22E70
