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 ...

In this work, we study the convergence of the finite element method when applied to the following parabolic equation: ut = div(|u|γ(x)Δu) + f(x, t), x ∈ Ω ⊂ Rm, t ∈]0, T]. Since the problem may be of ...

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In elementary algebra, those symbols (today written as Latin and Greek letters) represent ...

A UNSW Sydney mathematician has discovered a new method to tackle algebra's oldest challenge—solving higher polynomial equations. Polynomials are equations involving a variable raised to powers, such ...
