Survey on Recent Ulam Stability Results Concerning Derivations

open access: yesJournal of Function Spaces, 2016
This is a survey presenting the most significant results concerning approximate (generalized) derivations, motivated by the notions of Ulam and Hyers-Ulam stability.

On the general solution and hyperstability of the general radical quintic functional equation in quasi-β-Banach spaces

open access: yesJournal of Mathematical Analysis and Applications, 2018
The goal of this paper is to study the general solution of the following general radical quintic functional equation f ( a x 5 + b y 5 5 ) = r f ( x ) + s f ( y ) for f a mapping from the field of real numbers into a vector space, where a , b , r , s are

Hyperstable Sets with Voting and Algorithmic Hardness Applications

open access: yesCoRR, 2022
The noise stability of a Euclidean set $A$ with correlation $ρ$ is the probability that $(X,Y)\in A\times A$, where $X,Y$ are standard Gaussian random vectors with correlation $ρ\in(0,1)$. It is well-known that a Euclidean set of fixed Gaussian volume that maximizes noise stability must be a half space.

On Ulam's Type Stability of the Cauchy Additive Equation

open access: yesThe Scientific World Journal, 2014
We prove a general result on Ulam's type stability of the functional equation fx+y=fx+fy, in the class of functions mapping a commutative group into a commutative group. As a consequence, we deduce from it some hyperstability outcomes.

Absolute stability and hyperstability of a class of hereditary systems

open access: yesInformatica, 1998
This paper extends some basic results on absolute stability and hyperstability from linear plants subject to a wide class of nonlinear controllers to plants having delays in the state while being controlled by the same classes of nonlinear controllers.

Hyperstability in Electrofishing Catch Rates of Common Carp and Bigmouth Buffalo

open access: yes, 2022
Electrofishing catch per unit effort (CPUE) can be an effective index of relative abundance when CPUE is proportional to population density. However, the relationship between fish catch rates and density can be variable and not proportional because ...

HyperSteer: Activation Steering at Scale with Hypernetworks

open access: yesCoRR
Steering language models (LMs) by modifying internal activations is a popular approach for controlling text generation. Unsupervised dictionary learning methods, e.g., sparse autoencoders, can be scaled to produce many steering vectors, but lack guarantees on the individual efficacy of each vector and control over the coverage of relevant steering ...
