In this work, we address some issues related to products of graphs and products of modal logics. Our main contribution is the presentation of a necessary and sufficient condition for a countable and connected graph to be a product, using a property called intransitivity. We then proceed to describe this property in a logical language. First, we show that intransitivity is not modally definable ...

Descriptive theories of decision making are constrained by the need to explain the following behavioral phenomena: risk aversion, gambling, purchases of insurance, investment, the paradoxes of Allais and Ellsberg, intransitivity of preference, irregularities of choice, preference reversals, risk judgments, violations of branch independence, the difference between buying and selling prices, viol...

Do violations of classical rationality theory imply that agents are acting against their self-interest? To answer this question, we investigate whether completeness and transitivity necessarily hold when agents choose outcome rationally—that is, their choice sequences do not lead to dominated outcomes. We show that, because of the danger of money pumps and other manipulations, outcome rationali...

This paper discusses the status of Italian and Serbian clitic reflexives and reciprocals with respect to the phenomenon of split intransitivity. Assuming an analyses that treats clitics as non-argumental markers of the verb’s derived intransitivity, numerous proposals have been put forward as to whether clitic reflexives and reciprocals are unaccusative or unergative. The issue still appears as...
