We study a context -dependent problem that arises in an m-learning environment: how to print a document when being in a generic place. We implement a working solution, and argue about the general value of our approach. We examine the printing problem because it has a practical value, and at the same time it turns out to be a prototype for a class of other problems that can be encountered when m...

We explore the escape rate of a dimer crossing a potential barrier using both analytical and numerical approaches. We find that for small coupling strength k, the barrier hopping can be well approximated by a two step reaction scheme where one monomer hops over the barrier and is then followed by the other. In this regime the escape rate increases with k showing that the cooperativity between m...

ASYMPTOTIC VALUES AND THE GROWTH OF ANALYTIC FUNCTIONS IN SPIRAL DOMAINS J . E . BRENNAN AND A . L . VOLBERG In this note we present a simple proof of a theorem of Hornblower which characterizes those functions analytic in the open unit disk having asymptotic values at a dense set in the boundary. Our method is based on a kind of ó-mollification and may be of use in other problems as well .

Existing microstructure literature cannot explain the empirical evidence that bid-ask spreads can decrease with information asymmetry and ignores either information asymmetry or inventory risks. We develop a market making model that highlights the asset pricing impact of market makers’ capability of making offsetting trades in markets where both information asymmetry and inventory risk are sign...
