När innebär en noll-Wronskian linjärt beroende?
This thesis addresses a common misconception regarding the implications of an identically zero Wronskian on an interval. The starting point is the study of solutions to homogeneous ordinary differential equations, with particular focus on Liouville’s ...

Alexandria Engineering JournalThis paper used the flexible and efficient least squares residual power series method (LSRPSM) to solve the time-fractional derivative Cahn-Hilliard and Gardener equations. The LSRPSM combines the residual power series method (RPSM) and the least squares

Differential resolvents of minimal order and weight
International Journal of Mathematics and Mathematical Sciences, 2004 We will determine the number of powers of α that appear with nonzero coefficient in an α-power linear differential resolvent of smallest possible order of a univariate polynomial P(t) whose coefficients lie in an ordinary differential field and whose ...

Riesz Potentials for Korteweg-de Vries Solitons and Sturm-Liouville Problems
International Journal of Differential Equations, 2010 Riesz potentials (also called Riesz fractional derivatives) and their Hilbert transforms are computed for the Korteweg-de Vries soliton. They are expressed in terms of the full-range Hurwitz Zeta functions 𝜁+(𝑠,𝑎) and 𝜁−(𝑠,𝑎).

Jets of line bundles on curves and Wronskians
Journal of Pure and Applied Algebra, 2011 Let \(C\) be a smooth projective curve of genus \(g\). For a given line bundle \(L\in \text{Pic}^d(C)\) and \(h\geq 0\), \(J^hL\) denotes the bundle, of rank \(h+1\), of jets (or principal parts) of \(L\) of order \(h\). If \(0\leq i\leq h+1\), there is a natural epimorphism \(J^hL\rightarrow J^{h-i}L\), whose kernel is denoted by \(N_{h,i}(L)\).
