Alcune probabilità geometriche di reticoli nel piano
We consider, on the euclidean planeE 2, a lattice of fundamental regions that are regular polygons, triangles or parallelograms. We determin the probabilityp in order that a vertex of the latticeR belongs to a ci...

On the construction and enumeration of Hamiltonian graphs
In this paper we give a formula for enumerating the equivalent classes of orderly labeled Hamiltonian graphs under groupD n and two algorithms for constructuring these equivalent classes and all n...

The estimation of prior from fisher information
In Bayesian analysis, the maximum entropy prior is commonly used. But in some cases, the maximum entropy prior does not exist or has unpleasant jumps. In this paper, Fisher-information is used to measure the d...

Partial ferrers matrices
We introduce a class ofn×n matrices of 0’s and 1’s which can be regarded as generalizations of the classical Ferrers boards of rook theory. Assuming the matrices are fully indecomposable, we determine the minimum...

Non-Gaussian limit distributions of solutions of the many-dimensional Bürgers equation with random initial data
Limit distributions of solutions of the multidimensional Bürgers equation are found in the case where an initial condition is a random field of type χ2 of degreek with a long-range dependence.

The maximum number of intersections between two plane rectangular paths
We show that the maximum number of intersections between two plane rectangular paths with lengthsm andn, 2≤m≤n, is 4n+2, ifm=4 andn≡1(mod 3); and it ismn+1 otherwise.
