Operator splittings and spatial approximations for evolution equations [PDF]

open access: yes, 2009
The convergence of various operator splitting procedures, such as the sequential, the Strang and the weighted splitting, is investigated in the presence of a spatial approximation. To this end a variant of Chernoff's product formula is proved.

Engel conditions and symmetric tensors [PDF]

open access: yesLinear and Multilinear Algebra, 2011
In a recent study of Engel Lie rings, Serena Cicalo` and Willem de Graaf have given a practical set of conditions for an additively finitely generated Lie ring L to satisfy an Engel condition. We present a simpler and more direct proof of this fact.
