The time lag-luminosity relation: A consequence of the Amati relation? [PDF]

open access: yes, 2005
We use a simple pulse model to investigate the origin of the time lagluminosity relation (LLR) discovered by Norris et al.(ApJ, 534 (2000) 248). We show that, at least for single pulse bursts which satisfy both the hardness-intensity and the hardness ...

Disjunctive Multiple-Conclusion Consequence Relations [PDF]

open access: yes, 2019
The concept of multiple-conclusion consequence relation from [8] and [7] is considered. The closure operation C assigning to any binary relation r (dened on the power set of a set of all formulas of a given language) the least multiple-conclusion ...

Defining Cognitive Logics by Non-Classical Tableau Rules

open access: yesStudies in Logic, Grammar and Rhetoric, 2016
In the paper we propose a new approach to formalization of cognitive logics. By cognitive logics we understand supraclassical, but non-trivial consequence operations, defined in a propositional language.

Gödelova věta a relace logického důsledku

open access: yesTeorie vědy, 2010
Gödel’s Incompleteness Theorem and the Relation of Logical Consequence In his proof of the first incompleteness theorem, Kurt Gödel provided a method of showing the truth of specific arithmetical statements on the condition that all the axioms of a ...

Two-Variable Logic with Two Order Relations [PDF]

open access: yesLogical Methods in Computer Science, 2012
It is shown that the finite satisfiability problem for two-variable logic over structures with one total preorder relation, its induced successor relation, one linear order relation and some further unary relations is EXPSPACE-complete.

Sequent Systems for Consequence Relations of Cyclic Linear Logics

open access: yesBulletin of the Section of Logic
Linear Logic is a versatile framework with diverse applications in computer science and mathematics. One intriguing fragment of Linear Logic is Multiplicative-Additive Linear Logic (MALL), which forms the exponential-free component of the larger ...

Essentialist Blindness Would Not Preclude Counterfactual Knowledge

open access: yesPhilosophia Scientiæ, 2012
This paper does two things. First, it defends, against a potential threat to it, the claim that a capacity for essentialist knowledge should not be placed among the core capacities for counterfactual knowledge.

Direct experimental test of commutation relation via imaginary weak value

open access: yesPhysical Review Research, 2021
The canonical commutation relation is the hallmark of quantum theory, and Heisenberg's uncertainty relation is a direct consequence of it. Although various formulations of uncertainty relations have been tested in experiments a direct test of the ...

Complexity of Nonassociative Lambek Calculus with Classical and Intuitionistic Logic

open access: yesBulletin of the Section of Logic
The Nonassociative Lambek Calculus (NL) represents a logic devoid of the structural rules of exchange, weakening, and contraction, and it does not presume the associativity of its connectives. Its finitary consequence relation is decidable in polynomial
