Mathematical Finance, EarlyView.ABSTRACT We introduce a dynamic and stochastic interbank model with an endogenous notion of distress contagion, arising from rational worries about future defaults and ensuing losses. This entails a mark‐to‐market valuation adjustment for interbank claims, leading to a forward‐backward approach to the equilibrium dynamics whereby future default ...

Nijenhuis operator in contact homology and descendant recursion in symplectic field theory
, 2014 In this paper we investigate the algebraic structure related to a new type of correlator associated to the moduli spaces of $S^1$-parametrized curves in contact homology and rational symplectic field theory.

Mind &Language, EarlyView.Three main approaches exist for finessing the cognitive demands of Grice's model of communication (a notorious problem): namely, deflationism, modularity, and interpretivism. Here, I consider each in light of human metacommunication, a phenomenon that has been neglected in foundational discussions of Gricean communication.

Existence and stability of traveling waves for a competitive-cooperative recursion system
Electronic Journal of Differential Equations, 2020 This article concerns the existence and global stability of bistable traveling waves for a competitive-cooperative recursion system. We first show that the spatially homogeneous system associated with the competitive-cooperative recursion system

Noûs, EarlyView.ABSTRACT It is a truism of mathematics that differences between isomorphic number systems are irrelevant to arithmetic. This truism is deeply rooted in the modern axiomatic method and underlies most strands of arithmetical structuralism, the view that arithmetic is about some abstract number structure.

Why Are All the Sets All the Sets?
Noûs, EarlyView.ABSTRACT Necessitists about set theory think that the pure sets exists, and are the way they are, as a matter of necessity. They cannot explain why the sets (de rebus) are all the sets. This constitutes the Ur‐Objection against necessitism; it is the primary motivation cited by potentialists about set theory.

Noûs, EarlyView.ABSTRACT Purity is the principle that fundamental facts only have fundamental constituents. In recent years, it has played a significant (if sometimes implicit) role in metaphysical theorizing. A philosopher will argue that a fact [p]$[p]$ contains a derivative entity and cite Purity as a reason to deny that [p]$[p]$ is fundamental. I argue that recent

(Co‐)Reference All the Way Down: A Unified Theory of (Pro) Nominals in Ordinary English
Theoria, EarlyView.ABSTRACT This essay joins two themes, both arising from Kripke's inspiring ideas in the theory of reference. The first theme concerns reference in general. The second examines the notion of co‐reference and the role it plays in a unified theory of pronouns for natural language.

Continual decision‐making dynamics across biological organisms
Biological Reviews, Volume 101, Issue 3, Page 1059-1072, June 2026.ABSTRACT Decision‐making is a central function of adaptive behaviour in biological agents. However, strategies for adaptive decision‐making can vary substantially across species. Here, we aim to extend the comparative scope of decision‐making analyses to phylogenetically diverse organisms.

Quadratic Hedging of American Options Under GARCH Models
Journal of Futures Markets, Volume 46, Issue 6, Page 1079-1097, June 2026.ABSTRACT American options are widely traded in financial markets, yet there is a scarcity of literature on hedging in incomplete markets. In this paper, we derive optimal hedging ratios and option values using Local Risk Minimization (LRM) and Global Risk Minimization (GRM) hedging strategies through dynamic programming.
