Lyapunov-Type Inequality for the Hadamard Fractional Boundary Value Problem on a General Interval [a;b], (1≤a<b)

Authors: Zaid Laadjal
Comments: 12 Pages.

In this paper, we studied an open problem, where using two different methods, we obtained several results for a Lyapunov-type and Hartman-Wintner-type inequalities for a Hadamard fractional differential equation on a general interval [a;b],(1≤a<b) with the boundary value conditions.

The Isotropic Constant Depends Only on the Dimension of the Domain

Authors: Johan Aspegren
Comments: 2 Pages.

In this preprint we will prove that the isotropic constant depends only on the dimension of the domain. Thus we prove a result that implies the sharp isotropic constant conjecture.

Dynamic Equations for 2nd-Order Curves

Authors: Viktor Strohm
Comments: 4 Pages.

The motion of a point along an ellipse under the action of a generalized force is investigated. Result: differential equation of second-order curves with respect to the focus, differential equation of curves of the second order with respect to the center, general differential equation of second order curves. Several examples of the application of these equations are proposed.
