What are the underlying principles of how populations change over time? Two basic principles are involved, the idea of exponential growth and its ultimate control. The basics of population ecology ...

Inflection points are crucial to understanding the behavior of a function and its graph. In calculus, an inflection point is a point on the curve of the function where the concavity changes. In other ...

We develop an exponential spline interpolation method to solve the nonlinear Schrödinger equation. The truncation error and stability analysis of the method are ...
