On Strict Monotonicity of Continuous Solutions of Certain Types of Functional Equations

open access: yesCanadian Mathematical Bulletin, 1966
It is a commonplace that F is continuous on the cartesian square of the range of f if f is continuous and satisfies1say, for all real x, y (cf. e.g. [2]). A.D. Wallace has kindly called my attention to the fact, that this is trivial only if f is (constant or) strictly monotonic and asked for a simple proof of the strict monotonicity of f. The following

Minimal wave speed of traveling wavefronts in delayed Belousov-Zhabotinskii model

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
This paper is concerned with the traveling wavefronts of Belousov-Zhabotinskii model with time delay. By constructing proper upper and lower solutions and applying the theory of asymptotic spreading, the minimal wave speed is obtained under the weaker ...

Strictly strategy-proof auctions

open access: yes, 2020
A strictly strategy-proof mechanism is one that asks agents to use strictly dominant strategies. In the canonical one-dimensional mechanism design setting with private values, we show that strict strategy-proofness is equivalent to strict monotonicity ...

Knowability Relative to Information [PDF]

open access: yes, 2018
We present a formal semantics for epistemic logic, capturing the notion of knowability relative to information (KRI). Like Dretske, we move from the platitude that what an agent can know depends on her (empirical) information.

Strict monotonous asymptotic energetic stability. Part I: Theory

open access: yesIFAC Proceedings Volumes, 1999
Abstract The concept of strict monotonous asymptotic energetic stability (SMAES) of an equilibrium state of a time invariant nonlinear dynamic system is introduced by defining also energetic stability, energetic attraction and strict monotonous energetic attraction, as well as their domains, in a Lyapunov sense. The concept is important because it is

Entropy solutions of nonlinear elliptic equations with $L^1$-data and without strict monotonocity conditions in weighted Orlicz-Sobolev spaces

open access: yesJournal of Nonlinear Functional Analysis, 2021
. In this paper, we study the existence of entropy solutions for a class of nonlinear elliptic problems in weighted Orlicz-Sobolev spaces of with the form Au + g ( x , u ) = f , where A ( u ) = − div ( ρ ( x ) a ( x , u , ∇ u )) is a Leray-Lions operator

Lower Local Uniform Monotonicity in F-Normed Musielak–Orlicz Spaces

open access: yesAxioms
Lower strict monotonicity points and lower local uniform monotonicity points are considered in the case of Musielak–Orlicz function spaces LΦ endowed with the Mazur–Orlicz F-norm.

A categorial grammar of Spanish auxiliary chains

open access: yesIsogloss, 2022
Spanish auxiliary sequences as in Juan puede haber tenido que estar empezando a trabajar hasta tarde ‘Juan may have had to be starting to work until late’, traditionally termed auxiliary chains, have two properties that are not naturally captured in ...

δ-Cut Decision-Theoretic Rough Set Approach: Model and Attribute Reductions

open access: yesThe Scientific World Journal, 2014
Decision-theoretic rough set is a quite useful rough set by introducing the decision cost into probabilistic approximations of the target. However, Yao’s decision-theoretic rough set is based on the classical indiscernibility relation; such a relation ...
