We classify real two-dimensional orbits of conformal subgroups such that the orbits contain two circular arcs through a point. Such surfaces must be toric and admit a Möbius automorphism group of dimension at least two. Our theorem generalizes the cl…
The asymptotic behavior of solutions to a family of Dirichlet boundary value problems, involving differential operators in divergence form, on a domain equipped with a Finsler metric is investigated. Solutions are shown to converge uniformly to the d…
Suppose that
and
are closed smooth manifolds of dimension n that are homeomorphic. We prove that the spaces of smooth knots,
and
have the same homotopy
-type. In the four-dimensional case, this means that the spaces …
