Padua points — In polynomial interpolation of two variables, the Padua points are the first known example (and up to now the only one) of unisolvent point set (that is, the interpolating polynomial is unique) with minimal growth of their Lebesgue constant,… … Wikipedia
Cubic surface — A cubic surface is a projective variety studied in algebraic geometry. It is an algebraic surface in three dimensional projective space defined by a single polynomial which is homogeneous of degree 3 (hence, cubic). Cubic surfaces are del Pezzo… … Wikipedia

Lambert W function — The graph of W(x) for W > −4 and x < 6. The upper branch with W ≥ −1 is the function W0 (principal branch), the lower branch with W ≤ −1 is the function W−1. In mathematics, the Lambert W function, also called the Omega function or product… … Wikipedia
Linear dynamical system — In a linear dynamical system, the variation of a state vector (an N dimensional vector denoted mathbf{x}) equals a constant matrix(denoted mathbf{A}) multiplied by mathbf{x}. This variation can take two forms: either as a flow, in which mathbf{x} … Wikipedia
