چکیده

Let G3−out denote the random graph on vertex set [n] in which each vertex chooses 3 neighbors uniformly at random. Note that G3−out has minimum degree 3 and average degree 6. We prove that the probability that G3−out is Hamiltonian goes to 1 as n tends to infinity.

A ug 2 00 9 HAMILTON DECOMPOSITIONS OF REGULAR TOURNAMENTS

We show that every sufficiently large regular tournament can almost completely be decomposed into edge-disjoint Hamilton cycles. More precisely, for each η > 0 every regular tournament G of sufficiently large order n contains at least (1/2 − η)n edge-disjoint Hamilton cycles. This gives an approximate solution to a conjecture of Kelly from 1968. Our result also extends to almost regular tournam...

Loose Hamilton Cycles in Random 3-Uniform Hypergraphs

In the random hypergraph H = Hn,p;3 each possible triple appears independently with probability p. A loose Hamilton cycle can be described as a sequence of edges {xi, yi, xi+1} for i = 1, 2, . . . , n/2 where x1, x2, . . . , xn/2, y1, y2, . . . , yn/2 are all distinct. We prove that there exists an absolute constant K > 0 such that if p > K logn n then lim n→∞ 4|n Pr(Hn,p;3 contains a loose Ham...

A pr 2 00 9 Regime Switching Volatility Calibration by the Baum - Welch Method by Sovan Mitra

Regime switching volatility models provide a tractable method of modelling stochastic volatility. Currently the most popular method of regime switching calibration is the Hamilton filter. We propose using the Baum-Welch algorithm, an established technique from Engineering, to calibrate regime switching models instead. We demonstrate the Baum-Welch algorithm and discuss the significant advantage...

On the number of hamilton cycles in a random graph

Let a random graph G be constructed by adding random edges one by one, starting with n isolated vertices. We show that with probability going to one as n goes to infinity, when G first has minimum degree two, it has at least (logn)^ * distinct hamilton cycles for any fixed e > 0. §1, Introduction Let V = {lf2,...,n} and consider the random graph process (Bollobas [3]) G0,Gr ....G^, v = (£) wher...

This is a short exposition—mostly by way of the toy models " double logarithm " and " triple logarithm " —which should serve as an introduction to the article [3] in which we establish a connection between multiple polylogarithms, rooted trees and algebraic cycles.
