On compositions and triality.

- R. Sridharan, R. Parimala, M. -A. Knus

On the discriminant of an involution

- A. Knus, R. Parimala, R. Sridharan

In recent papers [KPS1], [KPS2] and [KPS3] the authors gave some applications of the reduced pfaffian of a central simple algebra with involution or, more generally, of an Azumaya algebra. In [KPS3],… Expand

The Minimum Weight Rooted Arborescence Problem: Weights on ARCS Case

- V. V. Rao, R. Sridharan
- Mathematics
- 1 May 1992

In a rooted acyclic graph, G, there exits, in general, several rooted (not necessarily spanning) arborscences. Depending on whether the graph has weights on nodes, on arcs, or on both, it is possible… Expand
