Classical (real) hedgehogs can be regarded as the geometrical realiza-tions of formal di¤erences convex bodies in R n+1. Like bodies, identi…ed with their support functions. Adopting a pro-jective viewpoint, we prove that any holomorphic function h : C n ! 'support function' complex hedgehog H In same vein, introduce notion evolute such 2 , and natural (but apparently hitherto unknown) curvatur...

Wireless Local Area Networks (WLAN) has attracted significant interest to support real-time communication. The most promising solution was recently published as IEEE 802.11e, which provide traffic differentiation. However, that solution still has an inadequate behavior to support real-time applications. In this paper, we propose a new traffic separation mechanism for IEEE 802.11e networks. Such...
