Semisimple filtrations of tilting modules for algebraic groups
… semisimple filtrations of minimal length (Loewy series) of tilting modules. We first demonstrate a criterion for determining when tilting modules for arbitrary quasi-hereditary algebras are rigid, i.e. have a unique Loewy series. Our criterion involves checking that $T(\lambda)$ does not …

Morita Stable Equivalence of Certain Algebras
… conjecture holds for such algebras of Loewy length at most 3. This extends earlier works of R. Martinez Villa and of T. Aiping for Morita stable equivalences.

Completely Positive Matrices Over Semirings and Their CP-rank
… the CP-rank of A. In 1994, Drew, Johnson and Loewy conjectured that the CP-rank of n x n real completely positive matrices of order n ≥ 4 is bounded above by [n²/4]. There was some evidence in support of this conjecture. However, Bomze and his co-workers (2014) disproved this conjecture for …

Three-Dimensional Unsteady Hydrodynamics of Tidal Turbines
Tidal power is an emerging industry in the renewable energy sector; a development which is uniquely beneficial to the United Kingdom, which has a significant tidal resource and a mature knowledge base for turbine technology. One of the challenges facing the tidal industry is the harsh nature of the …
