A risk-averse newsvendor with law invariant coherent measures of risk
For general law invariant coherent measures of risk, we derive an equivalent representation of a risk-averse newsvendor problem as a meanrisk model. We prove that the higher the w...

Gear composition and the stable set polytope
We present a new graph composition that produces a graph G from a given graph H and a fixed graph B called gear and we study its polyhedral properties. This composition yields cou...
