We construct an index theorem for smooth infinite economies that shows that generically the number of equilibria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria.

We present a simple proof of existence of subgame perfect equilibria in games with perfect information.

Lévy driven term structure models have become an important subject in the mathematical finance literature. This paper provides a comprehensive analysis of the Lévy driven Heath–Jarrow–Morton type term structure equation. This includes a full proof of existence and uniqueness in particular, which seems to have been lacking in the finance literature so far.

Authorship of bioscientific papers is a serious business. Most journals have policies that encourage transparency, making it clear who did what, but some authors take it less seriously than editors might like, and indexers don’t always get it right. Searching for common abbreviations (⇓) in PubMed (1809–2017), Embase (1974–2017), Ovid Medline (1946–2017), Philosopher’s Index (1966–2016), and Ps...

The most common philosophical view about the notion of existence is that it is a second-order property or existential quantification. A less common view is that existence is a (first-order) property of 'existent' as opposed to 'nonexistent' (past or merely intentional) objects. An even less common view is that existence divides into different 'modes of being' for different sorts of entities. In...
