We develop parametric classes of covariance functions on linear networks and their extension to graphs with Euclidean edges, that is, graphs with edges viewed as line segments or more general sets ...

‘Higher-order functions’ is a fancy term for functions that take other functions as arguments or that return functions. Very powerful!

The graph of a function f is the set of all points (inputs, outputs) = (x,y) in the plane which satisfy the equation y=f (x). You can move the input below and see how the graph give a visual ...

The approximation of the Ihara zeta function via the normalized version on finite graphs in the sense of Benjamini and Schramm follows as a special case. Our framework not only unifies corresponding ...

A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph - points are plotted as coordinates and joined by either a ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

With static graphs and equations, it's possible to get a handle on the rules of what various functions do and mean.
