Geometric Topology Seminar online via Zoom, Moscow
Topology studies properties that are invariant under homeomorphism and
its standard variations
(diffeomorphism, piecewise linear homeomorphism, homeomorphism of pairs,
fiberwise homeomorphism, etc.)
Geometric topology confines its attention to spaces that are accessible
to geometric intuition
(for example, subsets of Euclidean spaces $\mathbb{R}^n$) and proceeds from
elementary questions that have
intuitive geometric meaning. Yet methods used to solve these questions
can be far from elementary
and can dive deeply into other fields (algebraic topology, group theory,
algebraic Ktheory,
general topology, metric geometry, representation theory, functional
analysis, etc.)
As an illustration, here are five old unsolved problems of geometric
topology with short statements.
 Schoenflies Problem: Can the 3sphere be piecewise linearly (or
smoothly) knotted in $\mathbb{R}^4$?
 Rolfsen's Problem: Is every knot (=embedding of a circle in $\mathbb{R}^3$)
isotopic (=homotopic through knots)
to the trivial knot?
 Fenn's Problem: Does every 2dimensional contractible finite
simplicial complex piecewise linearly
embed in $\mathbb{R}^4$?
 Borsuk's Problem: Does every $n$dimensional contractible, locally
contractible compact metric space
embed in $\mathbb{R}^{2n}$?
 Hilbert–Smith Problem: Does there exist a free action of the group of
$p$adic integers on a manifold?
