Stability of -Jordan Homomorphisms from a Normed Algebra to a Banach Algebra
Abstract and Applied Analysis, 2013 We establish the hyperstability of -Jordan homomorphisms from a normed algebra to a Banach algebra, and also we show that an -Jordan homomorphism between two commutative Banach algebras is an -ring homomorphism.

Synergies between price and life history enhance extinction risk in open‐access fisheries
Fish and Fisheries, Volume 25, Issue 6, Page 972-984, November 2024.Abstract There have been few documented extinctions of fished species, but many bioeconomic models predict that open‐access incentives make extinction possible. Open‐access multi‐species fisheries can cause species' extinction if other, faster‐growing species maintain profits at fatal effort levels.

MathematicsIn this paper, we deduce some hyperstability results for a generalized class of homogeneous Pexiderized functional equations, expressed as ∑ρ∈Γfxρ.y=ℓf(x)+ℓg(y), x,y∈M, which is inspired by the concept of Ulam stability.

On Some Recent Developments in Ulam's Type Stability
Abstract and Applied Analysis, 2012 We present a survey of some selected recent developments (results and methods) in the theory of Ulam's type stability. In particular we provide some information on hyperstability and the fixed point methods.

CES Transactions on Electrical Machines and Systems, 2017 q-axis rotor flux can be chosen to form a model reference adaptive system (MRAS) updating rotor time constant online in induction motor drives. This paper presents a stability analysis of such a system with Popov's hyperstability concept and small-signal

Hyperstate Space Graphs for Automated Game Analysis [PDF]
2019 IEEE Conference on Games (CoG), 2019 Automatically analysing games is an important challenge for automated game design, general game playing, and co-creative game design tools. However, understanding the nature of an unseen game is extremely difficult due to the lack of a priori design knowledge and heuristics. In this paper we formally define hyperstate space graphs, a compressed form of

An assessment of potential interventions to reduce the totoaba illegal trade market
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract The illegal trade in totoaba (Totoaba macdonaldi) is causing adverse social, ecological, and economic impacts. This illegal activity is accelerating the overexploitation of totoaba and pushing the critically endangered vaquita (Phocoena sinus) closer to extinction.

Discrete Dynamics in Nature and Society, 2017 This paper formulates an “ad hoc” robust version under parametrical disturbances of the discrete version of the Kalman-Yakubovich-Popov Lemma for a class of positive hybrid dynamic linear systems which consist of a continuous-time system coupled with a ...

Catch uncertainty and recreational fishing attraction: Propositions and future research directions
Fish and Fisheries, Volume 25, Issue 5, Page 761-780, September 2024.Abstract Why do people fish for recreation? Social science literature suggests that both catch (e.g., number or sizes of fish) and non‐catch dimensions (e.g., nature experience, temporary escape) play a role. After reviewing the literature from environmental psychology, neuroscience, anthropology, recreational fisher motivation research as well as ...
