Existence and bounds of growth constants for restricted walks, surfaces, and generalisations
Sun Woo P. Kim, Gabriele Pinna
We introduce classes of restricted walks, surfaces and their generalisations. For example, self-osculating walks (SOWs) are supersets of self-avoiding walks (SAWs) where edges are…

Approximation theory for Green's functions via the Lanczos algorithm
Gabriele Pinna, Oliver Lunt, Curt von Keyserlingk
It is known that Green's functions can be expressed as continued fractions; the content at the -th level of the fraction is encoded in a coefficient , which can be recursiv…
