On a coloured tree with non i.i.d. random labels
(2010) In Statistics and Probability Letters 80(2324). p.18961903 Abstract
 We obtain new results for the probabilistic model introduced in Menshikov et al. (2007) and Volkov (2006) which involves a ddary regular tree. All vertices are coloured in one of dd distinct colours so that dd children of each vertex all have different colours. Fix d2d2 strictly positive random variables. For any two connected vertices of the tree assign to the edge between them a label which has the same distribution as one of these random variables, such that the distribution is determined solely by the colours of its endpoints. A value of a vertex is defined as a product of all labels on the path connecting the vertex to the root. We study how the total number of vertices with value of at least xx grows as x↓0x↓0, and apply the results... (More)
