Monotone iterations method for fractional diffusion equations

open access: yesМатематичні Студії, 2022
In recent years, there has been a growing interest on non-local models because of their relevance in many practical applications. A widely studied class of non-local models involves fractional order operators.

Comparison of polynomial-time reducibilities

open access: yesProceedings of the sixth annual ACM symposium on Theory of computing - STOC '74, 1974
AbstractVarious forms of polynomial time reducibility are compared. Among the forms examined are many-one, bounded truth table, truth table and Turing reducibility. The effect of introducing nondeterminism into reduction procedures is also examined.

Analysis and comparison of the stability of discrete-time and continuous-time linear systems

open access: yesArchives of Control Sciences, 2016
The asymptotic stability of discrete-time and continuous-time linear systems described by the equations xi+1 = Ākxi and x(t) = Akx(t) for k being integers and rational numbers is addressed. Necessary and sufficient conditions for the asymptotic stability

Modeling Yield Risk under Technological Change: Dynamic Yield Distributions and the U.S. Crop Insurance Program

open access: yesJournal of Agricultural and Resource Economics, 2011
The objective of this study is to evaluate the risk associated with major agricultural commodity yields in the United States. We are particularly concerned with the nonstationary nature of the yield distribution, which arises primarily as a result of ...

Comparison theorems for exit times [PDF]

open access: yesGeometric and Functional Analysis, 2001
Let \(\mathbb M_{\kappa}\) be the sphere, the Euclidean space or the hyperbolic space, with curvature \(\kappa\), and \(X_t\) a Brownian motion on \(\mathbb M_{\kappa}\). If \(A\) is a Borel set of finite volume and \(T_A:=\inf\{t>0:\;X_t\not\in A\}\), denote by \(u_A(t,x)\) the probability \(P_x\{T_A>t\}\), where \(x\) is the starting point of \(X_t\).

An extended Halanay inequality of integral type on time scales

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
In this paper, we obtain a Halanay-type inequality of integral type on time scales which improves and extends some earlier results for both the continuous and discrete cases. Several illustrative examples are also given.
