This paper proves that if points $Z_1,Z_2,...$ are chosen independently and identically using some measure $\mu$ from the unit circle in the complex plane, with $p_n(z) = (z-Z_1)(z-Z_2)...(z-Z_n)$, th...
On the existence of paths between points in high level excursion sets of Gaussian random fields

The structure of Gaussian random fields over high levels is a well researched and well understood area, particularly if the field is smooth. However, the question as to whether or not two or more poin...

Abstract: For a finite set of points $P$ in $R^d$, the function $d_P:R^d \to R_+$ measures Euclidean distance to the set $P$. We study the number of critical points of $d_P$ when $P$ is random. In par...
A small probabilistic universal set of starting points for finding roots of complex polynomials by Newton's method

We specify a small set, consisting of O(d(log log d)2) points,that intersects the basins under Newton's method of all roots of all (suitably normalized) complex polynomials of xed degrees d, with arb...
