A Critical Examination of Ibn-Sina’s Theory of the Conditional Syllogism
This paper will examine Ibn Sina’s theory of the Conditional Syllogism from a purely logical point of view, and will lay bare the principles he adopted for founding his theory, and the reason why the newly introduced part of his logic remained undeveloped and eventually was removed from the texts of logic in the later Islamic tradition. As a preliminary discussion, this paper briefly examines I...
متن کاملSolvability of an impulsive boundary value problem on the half-line via critical point theory
In this paper, an impulsive boundary value problem on the half-line is considered and existence of solutions is proved using Minimization Principal and Mountain Pass Theorem.
متن کاملOn a class of systems of n Neumann two-point boundary value Sturm-Liouville type equations
Employing a three critical points theorem, we prove the existence ofmultiple solutions for a class of Neumann two-point boundary valueSturm-Liouville type equations. Using a local minimum theorem fordifferentiable functionals the existence of at least one non-trivialsolution is also ensured.

متن کاملA variational approach to the problem of oscillations of an elastic half cylinder
This paper is devoted to the spectral theory (more precisely, tothe variational theory of the spectrum) of guided waves in anelastic half cylinder. We use variational methods to investigateseveral aspects of propagating waves, including localization (seeFigure 1), existence criteria and the formulas to find them. Weapproach the problem using two complementary methods: Thevariational methods fo...
