This paper addresses a question about the existence of certain types of homeomorphisms (specifically, cw-expansive homeomorphisms) on compact surfaces. The key contribution is the construction of such homeomorphisms on surfaces of higher genus (genus >= 0), providing an affirmative answer to a previously posed question. The paper also provides examples of 2-expansive but not expansive homeomorphisms and cw2-expansive homeomorphisms that are not N-expansive, expanding the understanding of these properties on different surfaces.
Key Takeaways
- •Provides an affirmative answer to a question about the existence of cw-expansive homeomorphisms.
- •Constructs examples on surfaces of higher genus.
- •Offers new examples of 2-expansive but not expansive homeomorphisms.
- •Presents examples of cw2-expansive homeomorphisms that are not N-expansive.
