Scaling-invariant Functions versus Positively Homogeneous Functions [PDF]
Journal of Optimization Theory and Applications, 2021 Scaling-invariant functions preserve the order of points when the points are scaled by the same positive scalar (with respect to a unique reference point). Composites of strictly monotonic functions with positively homogeneous functions are scaling-invariant with respect to zero.

Scaled Density Functional Theory Correlation Functionals [PDF]
The Journal of Physical Chemistry A, 2007 We show that a simple one-parameter scaling of the dynamical correlation energy estimated by the density functional theory (DFT) correlation functionals helps increase the overall accuracy for several local and nonlocal functionals. The approach taken here has been described as the "scaled dynamical correlation" (SDC) method [Ramachandran, J.

Journal of the Australian Mathematical Society, 1960 We consider real-valued functions ƒ(x) which are defined for all sufficiently large real numbers x. In discussing the behaviour of such functions as x → + ∞, it is useful to compare ƒ with the functions of some “comparison scale”. The early work in this field was due to Du Bois-Reymond (see, for example, (2), (3)).

On Central Branch/Reinsurance Risk Networks: Exact Results and Heuristics
Risks, 2018 Modeling the interactions between a reinsurer and several insurers, or between a central management branch (CB) and several subsidiary business branches, or between a coalition and its members, are fascinating problems, which suggest many interesting ...

Ostrowski type inequalities for exponentially s-convex functions on time scale
AIMS Mathematics, 2022 In this paper we establish some new inequalities of Ostrowski type for exponentially s-convex functions and s-convex functions on time scale. We also make comparison of our new results with already existing results by imposing some conditions.

Optimal Bail-Out Dividend Problem with Transaction Cost and Capital Injection Constraint
Risks, 2019 We consider the optimal bail-out dividend problem with fixed transaction cost for a Lévy risk model with a constraint on the expected present value of injected capital.

An inertial range length scale in structure functions [PDF]
, 2000 It is shown using experimental and numerical data that within the traditional inertial subrange defined by where the third order structure function is linear that the higher order structure function scaling exponents for longitudinal and transverse ...

Mixed Periodic-Classical Barrier Strategies for Lévy Risk Processes
Risks, 2018 Given a spectrally-negative Lévy process and independent Poisson observation times, we consider a periodic barrier strategy that pushes the process down to a certain level whenever the observed value is above it.
