Bounded convolutions with binomial coefficients
No, this is unrelated to the tie-knot thing; it's for a complexity analysis of an algorithm. |

Intuitionistic algebraic topology?
The context I'm working on is, to be more exact, what happens if I do topology internal to a particular topos of sheaves. |

From complexity to topology after a CS PhD
In particular, by stepping stone I mean to look for computational topologists who are interested in more complexity knowhow in their own workgroups, and use your participation in a postdoc in such a group as a way to bootstrap yourself into computational topology. After 2-3 years you'll be prolific in your new field instead. It is a gamble, but it is far from impossible. |

From complexity to topology after a CS PhD
I shifted after my PhD: from computational homological algebra to computational and applied algebraic topology. It took several years, and I have yet to see if my career eventually benefitted from it, but if anything I'd recommend trying to get contacts now to help you through, and to make your postdoc time a stepping stone for the shift. |

A generalization of a group isomorphism.
Does $a=h\text{coker}(k)$ even exist? It seems to me that $\text{coker}(k)$ should be a subobject of $G$, while $h$ takes input from $H$. |
