Ambient isotopy of the diagonal submanifold in product space

Given a closed manifold $M^n$ and its $k$-fold product space $M^n\times\cdots\times M^n$,Can the diagonal submanifold $\Delta:=\{(m,\cdots,m)\in (M^n)^k\mid m\in M\}$ be isotopied to the submanifold $...

Reference for a topological result

I am reading the short paper due to Erdös and Bollobás "On a Ramsey-Turán type problem", where they obtain a lower bound for the number of edges on an $n$-graph without $K_4$ as a subgraph ...

Torelli group of a punctured elliptic curve

Let $T_{g,n}$ be the Torelli group of a $n$-punctured surface $S=\overline{S}\setminus\{x_1,\ldots,x_n\}$, with $\overline S$ orientable, closed and of genus $g$. By definition, $T_{g,n}$ is the ...

Topology of manifolds and transition functions

let me start by describing some examples which may well demonstrate the motivation: A manifold is obtained by glueing together Euclidean spaces, and there is a transition function on the overlap of ...

Construct a homeomorphism of a surface that sends a subsurface to another subsurface

Let S be a compact orientable surface. Let A and B be two subsurfaces of S that have the same signature. How to check if there is a homeomorphism of S that sends A to B and if so, find one? Here a ...

Constructing Invariant Lamination of a Pseudo-Anosov Given By Dehn Twists

The simplest case of a well known theorem of Penner states that given a pair of filling curves, a positive twist about one curve together with a negative twist about the other curve is a pseudo-anosov ...

First introduction of horofunctions

Let $(X,d)$ be a metric space. An (intern) horofunction is a function of the form $h_y:x\mapsto d(x,y)-d(x_0,y)$, where $x_0$ is a fixed point. Now, the map $y\mapsto h_y$ is one-to-one and continuous ...

when is "fibering" preserved under homotopy equivalence

Suppose I have an oriented $F$ bundle over $B$ with total space $E$ (all of the three are closed manifolds) and i have a closed manifold $E'$ which is homotopy equivalent to $E$.Is there any condition ...
