Here we pursue Cantor’s theory of cardinalities of infinite sets a bit more deeply. We also begin to take a more sophisticated approach in that we identify which results depend upon the Axiom of Choice and strive to give proofs which avoid it when possible. However, we defer a formal discussion of the Axiom of Choice and its equivalents to a later installment, so the reader who has not encounte...

This article studies the role of installment payments in relationships characterized by moral hazard and sunk costs. We rule out vertical integration and payments contingent on the product of the contractor. Instead, each payment is negotiated as and when made. In such circumstances, an initial (down)payment serves to redress the weakness of the contractor in ex post renegotiations. Ifhigher ef...

In this paper we consider scheduling distributed divisible computations in systems with hierarchical memory for energy and time performance criteria. Hierarchical memory allows to conduct computations on big data sets using out-of-core processing instead of coercing application data t into core storage. However, out-of-core computations are more costly both in time and energy. A model for sched...
