- Continuous vs Discrete Variables - Mathematics Stack Exchange
Both discrete and continuous variables generally do have changing values—and a discrete variable can vary continuously with time I am quite aware that discrete variables are those values that you can count while continuous variables are those that you can measure such as weight or height
- Topological properties preserved by continuous maps
You'll find topological properties with indication of whether they are preserved by (various kinds of) continuous maps or not (such as open maps, closed maps, quotient maps, perfect maps, etc ) For mere continuous most things have been mentioned: simple covering properties (variations on compactness, connectedness, Lindelöf) and separability
- Why is the determinant continuous? - Mathematics Stack Exchange
Here you want to refer to the topology of the latter as a normed space, which does not depend on the norm since they are all equivalent in finite dimension Then the determinant is a polynomial in the coefficients, so it is continuous by composition of continuous maps
