High-dimensional tennis balls

Combinatorial Theory, 2022
We show that there exist constants $ , >0$ such that for every positive integer $n$ there is a continuous odd function $f:S^m\to S^n$, with $m\geq n$, such that the $ $-expansion of the image of $f$ does not contain a great circle. We also show how this result is connected to a conjecture of Vitali Milman about well-complemented almost ...
