I present a calculation of the one particle deep inelastic cross section in the target fragmentation region in (\phi^3)_6. The renormalized cross section gets a large logarithmic correction whose coefficient is precisely the scalar DGLAP…

Fractal percolation exhibits a dramatic topological phase transition, changing abruptly from a dust-like set to a system spanning cluster. The transition points are unknown and difficult to estimate. In many classical percolation models the…
