If you know something about point-set topology and properties of Euclidean spaces, please do me a favor and look at this problem. It is rather elementary and the main question can be summarized as
Does there exist a bijection such that
- Whenever is connected in the standard topology, so is
- is not continuous?
See the link above for more details.
The question has be bothering me for a few years now; and it is sufficiently far outside my main research interest that I hardly devote any time thinking about it.
I am an assistant professor in the mathematics department at Michigan State University. My research combines analytic and geometric techniques to study nonlinear evolutionary partial differential equations that arise in physical and geometric contexts. I am particularly interested in situations where wave-like phenomena arise, such as general relativity, fluids, and the physics of elastic membranes and solids.
