My first contact with Dr Kelly as a person was in 1965 when he taught two subjects to the Pure Mathematics Honours year at Sydney: category theory and topology. I found his
For the proof of Lemma 3 below we need a few facts on (ho- mogeneous) linear recurrence sequences with constant coefficients, for short... Indeed, we may even

Proof : The only problem is to prove formula (4), that is to prove that u is the sum of its Taylor expansion with respect to λ. In the case where A is a complex Banach algebra,
In section 4 we use this coupling to show the uniqueness of the stationary interface, and then finish the proof of theorem 12. Stochastic compactness for the width of
Our proof follows recent work by Denisov and Wachtel who used mar- tingale properties and a strong approximation of random walks by Brownian motion.. Therefore, we are able to

In theoretical physics Gauss–Bonnet curvatures are known as a Lagrangian of pure Lovelock gravity, Gauss–Bonnet gravity or Lanczos gravity. the integer part of one half the
