We study a natural discrete Bochner-type inequality on graphs, and explore its merit as a notion of “curvature” in discrete spaces. An appealing feature of this discrete version of the so-called Γ2-calculus (of Bakry-Émery) seems to be that it is fairly straightforward to compute this notion of curvature parameter for several specific graphs of interest –(More)
Along with the emergence and public acceptance of different operating systems and platforms during the past few years, came the need for quick cross-platform development solutions. This need was partially fulfilled by cross-compilers, due to the variety of underlying hardware. Virtual machines (VMs), whose technology was revived by the evolution of hardware(More)
