Zigzag persistent homology and real-valued functions
We study the problem of computing zigzag persistence of a sequence of homology groups and study a particular sequence derived from the levelsets of a real-valued function on a top...

I-PMIP: an inter-domain mobility extension for proxy-mobile IP
Proxy Mobile IP (PMIP) provides a solution for networkbased localized mobility management which in contrast to host-based mobility solutions, like Mobile IP (MIP), does not requir...
