On Generalized Flett's Mean Value Theorem [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
We present a new proof of generalized Flett's mean value theorem due to Pawlikowska (from 1999) using only the original Flett's mean value theorem. Also, a Trahan-type condition is established in general case.

Flett's mean value theorem in topological vector spaces [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We prove some generalizations of Flett's mean value theorem for a class of Gateaux differentiable functions f:X→Y, where X and Y are topological vector spaces.

On a functional equation related to a generalization of Flett's mean value theorem [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
In this paper, we characterize all the functions that attain their Flett mean value at a particular point between the endpoints of the interval under consideration. These functions turn out to be cubic polynomials and thus, we also characterize these.

A Cauchy-type generalization of Flett's theorem [PDF]

open access: yesDemonstratio Mathematica, 2021
We prove a Cauchy-type generalization of Flett’s theorem and note its geometric interpretations. Several other mean value theorems extending further the result, which involve both real and complex functions, are also proved.

On Flett’s mean value theorem [PDF]

open access: yesAequationes mathematicae, 2014
Mean value theorems play an important role in differential and integral calculus as they are a powerful tool for solving problems in mathematical analysis. The authors of the present paper provide a thorough study of Flett's mean value theorem of a real-valued function of one real variable.

The mean value theorem of Flett and divided differences

open access: yesJournal of Mathematical Analysis and Applications, 2004
Flett's mean value theorem reads as follows: If \(f\) is differentiable on \([a,b]\) and \(f'(a)=f'(b)\), then there exists a point \(c\in(a,b)\) such that \[ f(c)-f(a)=f'(c)(c-a).\tag{11} \] After a careful analysis of divided differences on multiple knots, the authors rewrite as \([a,c,c;f]\) \(=0\) and give condensed representations of other Flett ...

Conformable Flett’s theorem and Sahoo and Riedel theorem

open access: yesBalıkesir Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023
Since fractional analysis has attracted considerable interest by virtue of their ability to model complex phenomena, it is crucial to investigate properties of fractional derivatives. In this research, accordingly, we first give the extension of Flett's theorem and Sahoo and Riedel theorem to conformable derivative as a variety of conformable mean ...

AN EXTENSION OF A THEOREM OF FLETT

open access: yesDemonstratio Mathematica, 1999
\textit{T. M. Flett} [Math. Gaz. 42, 38-39 (1958)] proved the following variant of the Lagrange mean value theorem: If \(f\) is differentiable in \([a,b]\) with \(f'(a)=f'(b)\), then there is an \(\eta \in (a,b)\) such that \(f(\eta)-f(a) = (\eta-a) f'(\eta)\). This was refined by \textit{P. K. Sahoo} and \textit{T.

Some Variants of Wayment's Mean Value Theorem for Integrals

open access: yesSelecciones Matemáticas
This note deals with some variants of Wayment’s Mean Value Theorem for integrals. Our approach is rather elementary and does not use advanced techniques from analysis. The simple auxiliary functions were used to prove the results.
