Behavior of second order nonlinear differantial equations
International Journal of Mathematics and Mathematical Sciences, Volume 1, Issue 1, Page 1-12, 1978., 1978 Qualitative behavior of second order nonlinear differential equations with variable coefficients is studied. It includes properties such as positivity, number of zeroes, oscillatory behavior, boundedness and monotonicity of the solutions.

Open MathematicsWe study linear differential equations whose coefficients consist of products of powers of natural logarithm and general continuous functions. We derive conditions that guarantee the non-oscillation of all non-trivial solutions of the treated type of ...

Plato’s recollection argument in the "Philebus"
, 2018 Many scholars have denied that Plato’s argument about desire at Philebus 34c10–35d7 is related to his recollection arguments in the Meno and Phaedo, because it is concerned only with postnatal experiences of pleasure.

Applied Mathematics in Science and EngineeringThis work investigates the oscillatory behavior of neutral differential equations in the compulsory nonlinear case. We consider the noncanonical situation and establish a multi-condition criterion that is an extension of previous non-neutral results.

Robust preconditioners for $hp$-discontinuous Galerkin discretizations for elliptic problems
, 2018 Discontinuous Galerkin (DG) methods offer a very powerful discretization tool because they not only are suited for a wide range of partial differential equations but also because they support as well local mesh refinement as varying polynomial degrees ...
