equilibrium is always obtained. On the other hand, in the case of an even number of actions, every such game exhibits an infinite … number of Nash equilibria. As a special case, a proof of the uniqueness of the Nash equilibrium for the Rock …

spaces, there is a simple formula for the cyclomatic number, i.e., the dimension of cycle spaces of a model. We prove that … the cyclomatic number is the minimum number of cycle equations that must be checked to guarantee the existence of a common … prior, and explain why some cycle equations are automatically satisfied. There is an isomorphism taking cycles into cycle …

Equilibrium determines leverage, not just interest rates. Variations in leverage cause fluctuations in asset prices …. This leverage cycle can be damaging to the economy, and should be regulated. …

clusters could disconnect their cycle from the cycle of technologies, in order to insure their long term viability. For that … pathways of clusters.We show that clusters succeed in disconnecting their cycle from the cycle of technologies if and only if … they display resilience properties. Key-words : cluster, cycle, location externalities, knowledge, structural properties …
