Analysis of the probability distribution of photocount number of the onemode stochastic radiation
Yu. P. Virchenko, N. N. Vitokhina
The Mandel probability distribution of one-mode stochastic radiation photocounts is analized. Approximations of n-photon registration probabilities with guaranteed accuracy are obt…

Revision of upper estimate of percolation threshold on square lattice
Yu. P. Virchenko, Yu. A. Tolmacheva
The more exact upper estimate of the percolation threshold for the {\it site problem} on the quadratic lattice have been found on the basis of the cluster decompositio…

On the upper limit of percolation threshold in square lattice
Yu. P. Virchenko, Yu. A. Tolmacheva
The problem of percolation along sites of square lattice is studied. The number of contours being external boundaries for finite clusters has been estimated using geometric conside…
