Product splittings for p-compact groups

W. Dwyer, C. Wilkerson (1995)

Fundamenta Mathematicae

Similarity:

We show that a connected p-compact group with a trivial center is equivalent to a product of simple p-compact groups. More generally, we show that product splittings of any connected p-compact group correspond bijectively to algebraic splittings of the fundamental group of the maximal torus as a module over the Weyl group. These are analogues for p-compact groups of well-known theorems about compact Lie groups.

Optimal stationary policies inrisk-sensitive dynamic programs with finite state spaceand nonnegative rewards

Rolando Cavazos-Cadena, Raúl Montes-de-Oca (2000)

Applicationes Mathematicae

Similarity:

This work concerns controlled Markov chains with finite state space and nonnegative rewards; it is assumed that the controller has a constant risk-sensitivity, and that the performance ofa control policy is measured by a risk-sensitive expected total-reward criterion. The existence of optimal stationary policies isstudied within this context, and the main resultestablishes the optimalityof a stationary policy achieving the supremum in the correspondingoptimality equation, whenever the...
