Constants in the oscillation theory of higher order Sturm-Liouville differential equations

Electronic Journal of Differential Equations, 2002
We find the the exact value of a constant in some oscillation criteria for the higher order Sturm-Liouville differential equation $$ (-1)^{n}(t^alpha y^{(n)})^{(n)}=q(t)y . $$ We also study some general aspects in the oscillation theory of this equation.

Mixed boundary value problems involving Sturm–Liouville differential equations with possibly negative coefficients

Boundary Value Problems
This paper is devoted to the study of a mixed boundary value problem for a complete Sturm–Liouville equation, where the coefficients can also be negative. In particular, the existence of infinitely many distinct positive solutions to the given problem is

Phase transition in anisotropic holographic superfluids with arbitrary dynamical critical exponent z and hyperscaling violation factor $$\alpha $$ α

European Physical Journal C: Particles and Fields, 2017
Einstein-scalar-U(2) gauge field theory is considered in a spacetime characterized by $$\alpha $$ α and z, which are the hyperscaling violation factor and the dynamical critical exponent, respectively.

Principal solution in Weyl-Titchmarsh theory for second order Sturm-Liouville equation on time scales

Electronic Journal of Qualitative Theory of Differential Equations, 2017
A connection between the oscillation theory and the Weyl-Titchmarsh theory for the second order Sturm-Liouville equation on time scales is established by using the principal solution.
