spatial context, therefore, contiguity (interactivity or connectedness) is very important. In the real world, ‘connectedness …’ (interactivity or contiguity) is not a simple binary relationship that may capture the openness of the spatial entities to each other …

the absence of asymptotic arbitrage of the first kind is equivalent to the contiguity of sequence of objective … arbitrage of the second kind is equivalent to the contiguity of the sequence of lower envelopes of equivalent martingale … measures with respect to the sequence of objective probabilities. We express criteria of contiguity in terms of the Hellinger …
