Pseudo-Riemannian Algebraic Ricci Solitons on Four-Dimensional Lie Groups

Youssef Ayad

We investigate the conditions under which pseudo-Riemannian inner products induce pseudo-Riemannian algebraic Ricci solitons on four-dimensional Lie algebras. By analyzing the alge…

Isometry groups of simply connected nonunimodular Lie groups of dimension four

Youssef Ayad

For each left-invariant Riemannian metric on simply connected nonunimodular Lie groups of dimension four, we determine the full group of isometries.

Classification of left invariant Riemannian metrics on nonunimodular 4-dimensional Lie groups

Malika Ait Ben Haddou, Youssef Ayad

We classify, up to automorphism, left invariant Riemannian metrics on 4-dimensional simply connected nonunimodular Lie groups. This is equivalent to classifying, up to automorphism…

Isometry groups of simply connected unimodular 4-dimensional Lie groups

Youssef Ayad, Said Fahlaoui

We describe the full group of isometries of each left invariant Riemannian metric on the simply connected unimodular nilpotent or solvable (R)-type Lie groups of dimension four.
