The Kakeya Set Conjecture is True

Authors: Johan Aspegren
Comments: 5 Pages.

In this article we will prove the Kakeya set conjecture. In addition we will prove that in the usual approach to the Kakeya maximal function conjecture we can assume that the tube-sets are maximal. Third, we build a direct connection between line incidence theorems and Kakeya type conjectures.

Arithmetic of Analysis

Authors: Fayowole David Ayadi
Comments: 3 Pages.

Abstract:I can still remember my expression and feeling when we were asked to show that sup(A + B) = sup(A) + sup(B). It was an herculean task because the concept was too difficult to grasp with the use of approximation property until I discovered an easy route. In a bid to restrict my papers to just few pages, I will focus more on examples than theorems.

Riemann Integration On R^n

Authors: Fayowole David Ayadi, Olabiyi Tobi David, Oluwajoba Godsfavour Favour, Oluwusi Faith Tolu, Isaleye Dorcas, Olorunisola Femi Stephen
Comments: 13 Pages.

Throughout these discussions the numbers epsilon > 0 and delta > 0 should be thought of as very small numbers. The aim of this part is to provide a working definition for the integral of a bounded function f(x) on the interval [a, b]. We will see that the real number "f(x)dx" is really the limit of sums of areas of rectangles.

Existence of Solutions for Langevin Differential Equations Involving Two Fractional Orders on the Half-Line

Authors: Zaid Laadjal
Comments: 4 Pages.

In this paper, we study the existence and uniqueness of solutions for Langevin differential equations of Riemman-Liouville fractional derivative with boundary value conditions on the half-line. By a classical fixed point theorems, several new existence results of solutions are obtained.

Existence of Solutions for Fractional Langevin Equations with Boundary Conditions on an Infinite Interval

Authors: Zaid Laadjal
Comments: 5 Pages.

In this paper, we investigate the existence and uniqueness of solutions for the following fractional Langevin equations with boundary conditions $$\left\{\begin{array}{l}D^{\alpha}( D^{\beta}+\lambda)u(t)=f(t,u(t)),\text{ \ \ \ }t\in(0,+\infty),\\ \\u(0)=D^{\beta}u(0)=0,\\ \\ \underset{t\rightarrow+\infty}{\lim}D^{\alpha-1}u(t)=\underset{t\rightarrow+\infty}{\lim}D^{\alpha +\beta-1}u(t)=au(\xi),\end{array}\right.$$ where $1<\alpha \leq2$ and$\ 0<\beta \leq1,$ such that $1<\alpha +\beta \leq2,$ with $\ a,b\in\mathbb{R},$ $\xi \in\mathbb{R}^{+},$\ and $D^{\alpha}$, $D^{\beta }$ are the Riemman-Liouville fractional derivative. Some new results are obtained by applying standard fixed point theorems.
