Reflected generalized discontinuous BSDEs with rcll barrier and an obstacle problem of IPDE with nonlinear Neumann boundary conditions

open access: yesModern Stochastics: Theory and Applications, 2022
Reflected generalized backward stochastic differential equations (BSDEs) with one discontinuous barrier are investigated when the noise is driven by a Brownian motion and an independent Poisson measure.

Doubling measures, monotonicity, and quasiconformality [PDF]

open access: yesMathematische Zeitschrift, 2007
We construct quasiconformal mappings in Euclidean spaces by integration of a discontinuous kernel against doubling measures with suitable decay. The differentials of mappings that arise in this way satisfy an isotropic form of the doubling condition.

A view on weighted exponential entropy and examining some of its features [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
One of the alternative versions of Shannon entropy is a measure of information which is called exponential entropy. Shannon and exponential entropies depend only on the event probabilities.

Constrained Monotone Function Maximization and the Supermodular Degree [PDF]

open access: yes, 2014
The problem of maximizing a constrained monotone set function has many practical applications and generalizes many combinatorial problems. Unfortunately, it is generally not possible to maximize a monotone set function up to an acceptable approximation ...

λ–Algebra with Some of Their Properties

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2020
    The objective of this paper is, firstly, we study a new concept noted by algebra and discuss the properties of this concept. Secondly, we introduce a new concept related to the algebra such as smallest algebra.

Prevalent Behavior of Strongly Order Preserving Semiflows [PDF]

open access: yes, 2006
Classical results in the theory of monotone semiflows give sufficient conditions for the generic solution to converge toward an equilibrium or towards the set of equilibria (quasiconvergence).

Rank monotonicity in centrality measures [PDF]

open access: yesNetwork Science, 2017
AbstractA measure of centrality isrank monotoneif after adding an arcx→y, all nodes with a score smaller than (or equal to)yhave still a score smaller than (or equal to)y. If, in particular, all nodes with a score smaller than or equal toyget a score smaller thany(i.e., all ties withyare broken in favor ofy), the measure is calledstrictly rank monotone.

On a New Kind of Collection of Subsets Noted by δ–field and Some Concepts Defined on δ–field

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2019
     The objective of this paper is, first, study a new collection of sets such as field and we discuss the properties of this collection. Second, introduce a new concepts related to the field such as measure on field, outer measure on field and we ...

Nonparametric instrumental variable estimation under monotonicity [PDF]

open access: yes, 2014
The ill-posedness of the inverse problem of recovering a regression function in a nonparametric instrumental variable model leads to estimators that may suffer from a very slow, logarithmic rate of convergence. In this paper, we show that restricting the
