Functions weaker than continuous functions [PDF]

, 1972
Many properties which are characteristic of continuous function remain valid for several classes of non-continuous functions if appropriate limitations are imposed.

On compactness and connectedness of the paratingent [PDF]

, 2016
In this note we shall prove that for a continuous function \(\varphi : \Delta\to\mathbb{R}^n\), where \(\Delta\subset\mathbb{R}\),  the paratingent of \(\varphi\) at \(a\in\Delta\) is a non-empty and compact set in \(\mathbb{R}^n\) if and only if ...

Properties of Almost \(\omega\)-Continuous Functions

Journal of Advanced Studies in Topology, 2013
Summary: In [``Almost \(\omega\)-continuous functions'', Eur. J. Sci. Res. 8, No. 1, 43--47 (2005)], \textit{T. M. Nour} introduced and studied the notion of almost \(\omega\)-continuity in topological spaces. In this paper, we investigate some more properties of this type of continuity.

Some results on fuzzy hyperconnected spaces [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2017
This paper is a prolongation of the study of fuzzy hyperconnectedness. After studying the characteristic of fuzzy hyperconnectedness concerned with different concepts we ascertain an extension of one essential result of Park et al. (2003).

Double Fuzzy Ideal Multifunctions

Mathematics
In this paper, we introduce the notion of p,q-fuzzy local function and DF-ideal topological space. Also, we introduce the concepts DFU-ð-continuous and DFL-ð-continuous, almost ð-continuous, weakly ð-continuous and almost weakly ð-continuous ...

On nth-order differential operators with Bohr-Neugebauer type property

International Journal of Mathematics and Mathematical Sciences, 1987
Suppose B is a bounded linear operator in a Banach space. If the differential operator dndtn−B has a Bohr-Neugebauer type property for Bochner almost periodic functions, then, for any Stepanov almost periodic continuous function g(t) and any Stepanov ...

Bounded and almost automorphic solutions of a Liénard equation with a singular nonlinearity

Electronic Journal of Qualitative Theory of Differential Equations, 2008
We study some properties of bounded and $C^{(1)}$-almost automorphic solutions of the following Li\'enard equation: $$x'' + f(x)x' + g(x) = p(t), $$ where $p : {\bf R} \longrightarrow {\bf R}$ is an almost automorphic function, $f$, $g : (a,b ...

Almost sure exponential stability of the Euler–Maruyama approximations for stochastic functional differential equations [PDF]

, 2011
By the continuous and discrete nonnegative semimartingale convergence theorems, this paper investigates conditions under which the Euler–Maruyama (EM) approximations of stochastic functional differential equations (SFDEs) can share the almost sure ...
