Complex Variables
Using the definition of uniformly perfect sets in terms of convergent
sequences, we apply lower bounds for the Hausdorff content of a uniformly
perfect subset E of Rn to prove new explicit lower bounds for the
Hausdorff dimens...

Multiparty session types (MSTs) are a type-based approach to verifying
communication protocols. Central to MSTs is a projection operator: a partial
function that maps protocols represented as global types to
correct-by-construction implemen...

Trading pressure from one asset can move the price of another, a phenomenon
referred to as cross impact. Using tick-by-tick data spanning 5 years for 500
assets listed in the United States, we identify the features that make
cross-impact re...

Existing NAS methods suffer from either an excessive amount of time for
repetitive sampling and training of many task-irrelevant architectures. To
tackle such limitations of existing NAS methods, we propose a paradigm shift
