A comparison on the commutative neutrix convolution of distributions and the exchange formula

Adem Kiliçman — 2001

Czechoslovak Mathematical Journal

Let $\tilde{f}$ , $\tilde{g}$ be ultradistributions in $𝒵^{'}$ and let ${\tilde{f}}_{n} = \tilde{f} * δ_{n}$ and ${\tilde{g}}_{n} = \tilde{g} * σ_{n}$ where ${δ_{n}}$ is a sequence in $𝒵$ which converges to the Dirac-delta function $δ$ . Then the neutrix product $\tilde{f} ⋄ \tilde{g}$ is defined on the space of ultradistributions $𝒵^{'}$ as the neutrix limit of the sequence ${\frac{1}{2} ({\tilde{f}}_{n} \tilde{g} + \tilde{f} {\tilde{g}}_{n})}$ provided the limit $\tilde{h}$ exist in the sense that $\underset{n \to \infty}{N - l i m} \frac{1}{2} 〈 {\tilde{f}}_{n} \tilde{g} + \tilde{f} {\tilde{g}}_{n}, ψ 〉 = 〈 \tilde{h}, ψ 〉$ for all $ψ$ in $𝒵$ . We also prove that the neutrix convolution product $f ♦ * g$ exist in $𝒟^{'}$ , if and only if the neutrix product $\tilde{f} ⋄ \tilde{g}$ exist in $𝒵^{'}$ and the exchange formula $F (f ♦ * g) = \tilde{f} ⋄ \tilde{g}$ is then satisfied.

Open Mathematics

In this study, we introduce a new class of function called geodesic semi E-b-vex functions and generalized geodesic semi E-b-vex functions and discuss some of their properties.

Commutative neutrix convolution products of functions

Brian Fisher; Adem Kiliçman — 1994

Commentationes Mathematicae Universitatis Carolinae

The commutative neutrix convolution product of the functions $x^{r} e_{-}^{λ x}$ and $x^{s} e_{+}^{μ x}$ is evaluated for $r, s = 0, 1, 2, ...$ and all $λ, μ$ . Further commutative neutrix convolution products are then deduced.

Some commutative neutrix convolution products of functions

Brian Fisher; Adem Kiliçman — 1995

Commentationes Mathematicae Universitatis Carolinae

The commutative neutrix convolution product of the locally summable functions ${cos}_{-} (λ x)$ and ${cos}_{+} (μ x)$ is evaluated. Further similar commutative neutrix convolution products are evaluated and deduced.

On the non-commutative neutrix product $ln x_{+} \circ x_{+}^{- s}$

Brian Fisher; Adem Kiliçman; Blagovest Damyanov; J. C. Ault — 1996

Commentationes Mathematicae Universitatis Carolinae

The non-commutative neutrix product of the distributions $ln x_{+}$ and $x_{+}^{- s}$ is proved to exist for $s = 1, 2, ...$ and is evaluated for $s = 1, 2$ . The existence of the non-commutative neutrix product of the distributions $x_{+}^{- r}$ and $x_{+}^{- s}$ is then deduced for $r, s = 1, 2, ...$ and evaluated for $r = s = 1$ .
