In mathematics, a collocation method is a method for the numerical solution of ordinary differential equations, partial differential equations and integral equations.The idea is to choose a finite-dimensional space of candidate solutions (usually polynomials up to a certain degree) and a number of points in the domain (called collocation points), and to select that solution which satisfies the ...
In mathematics, a path in a topological space is a continuous function from a closed interval into . Paths play an important role in the fields of topology and mathematical analysis . For example, a topological space for which there exists a path connecting any two points is said to be path-connected .
PROPT uses a pseudospectral Collocation method (with Gauss or Chebyshev points) for solving optimal control problems. This means that the solution takes the form of a Polynomial, and this polynomial satisfies the DAE and the path constraints at the collocation points. In general PROPT has the following main functions:
Rigor is a cornerstone quality of mathematics, and can play an important role in preventing mathematics from degenerating into fallacies. well-behaved An object is well-behaved (in contrast with being Pathological ) if it satisfies certain prevailing regularity properties, or if it conforms to mathematical intuition (even though intuition can ...
A space of all maps from to X, with no distinguished point for the start of the paths, is called the free path space of X. [2] The maps from to X are called free paths. The path space P X {\displaystyle PX} is then the pullback of X I → X , χ ↦ χ ( 0 ) {\displaystyle X^{I}\to X,\,\chi \mapsto \chi (0)} along ∗ ↪ X {\displaystyle ...
Collocation methods for the solution of differential and integral equations are based on polynomial interpolation. The technique of rational function modeling is a generalization that considers ratios of polynomial functions.

The deleted comb space is not path connected since there is no path from (0,1) to (0,0): Suppose there is a path from p = (0, 1) to the point (0, 0) in D. Let f : [0, 1] → D be this path. We shall prove that f −1 {p} is both open and closed in [0, 1] contradicting the connectedness of this set.
