Truthmaker Semantics and Natural Language Semantics
ABSTRACT Truthmaker semantics is a non‐classical logical framework that has recently garnered significant interest in philosophy, logic, and natural language semantics. It redefines the propositional connectives and gives rise to more fine‐grained entailment relations than classical logic.

The Poincaré‐extended ab$\mathbf {a}\mathbf {b}$‐index
Abstract Motivated by a conjecture concerning Igusa local zeta functions for intersection posets of hyperplane arrangements, we introduce and study the Poincaré‐extended ab$\mathbf {a}\mathbf {b}$‐index, which generalizes both the ab$\mathbf {a}\mathbf {b}$‐index and the Poincaré polynomial.

ℓp$\ell ^p$ metrics on cell complexes
Abstract Motivated by the observation that groups can be effectively studied using metric spaces modelled on ℓ1$\ell ^1$, ℓ2$\ell ^2$ and ℓ∞$\ell ^\infty$ geometry, we consider cell complexes equipped with an ℓp$\ell ^p$ metric for arbitrary p$p$. Under weak conditions that can be checked locally, we establish non‐positive curvature properties of these

On equationally compact semilattices [PDF]
Although equationally compact semilattices have been completely characterized [4], the question of J. Mycielski "Is every equationally compact semilattice the retract of a compact topological semilattice?" has heretofore remained unanswered.

Exploring the Boundaries of Monad Tensorability on Set [PDF]
We study a composition operation on monads, equivalently presented as large equational theories. Specifically, we discuss the existence of tensors, which are combinations of theories that impose mutual commutation of the operations from the component ...

Studying the Theory of Hoops Through Some Type of Filters
It is known that the class of hoops is ideally determined, in the sense that every filter of any hoop H is a 1‐class of a unique congruence relation on H. This confirms that every filter in a hoop determines one and only one quotient structure. So, given a hoop H and a filter π of H, it is natural to question ourselves what should be the defining ...

ABSTRACT We can use “reason,” with its normative sense, as both a count noun (“there is a reason for her to Φ”) and a mass noun (“there is plenty of reason for her to Φ”). How are the count and mass senses of “reason” related? Daniel Fogal argues that the mass sense is fundamental: Just as lights are merely those things that give light and anxieties ...

On semilattices of groups whose arrows are epimorphisms
A q partial group is defined to be a partial group, that is, a strong semilattice of groups S=[E(S);Se,ϕe,f] such that S has an identity 1 and ϕ1,e is an epimorphism for all e∈E(S).

Routes to relevance: Philosophies of relevant logics
Abstract Relevant logics are a family of non‐classical logics characterized by the behavior of their implication connectives. Unlike some other non‐classical logics, such as intuitionistic logic, there are multiple philosophical views motivating relevant logics. Further, different views seem to motivate different logics. In this article, we survey five
