RT Journal Article T1 Some features of rank one real solvable cohomologically rigid lie algebras with a nilradical contracting onto the model filiform lie algebra Qn A1 Campoamor Stursberg, Otto-Rudwig A1 Oviaño García, Francisco AB The generic structure and some peculiarities of real rank one solvable Lie algebras possessing a maximal torus of derivations with the eigenvalue spectrum spec(t) =(1, k, k +1, ..., n + k-3, n +2k -3) for k [mayor o igual] 2 are analyzed, with special emphasis on the resulting Liealgebras for which the second Chevalley cohomology space vanishes. From the detailed inspection ofthe values k [menor o igual] 5, some series of cohomologically rigid algebras for arbitrary values of k are determined.
