Casals–Etnyre conjecture on infinitely many non-contact-isotopic embeddings
Casals–Etnyre conjecture. There are infinitely many formally contact isotopic embeddings of the standard $ST^*S^{n-1}$ into $(S^{2n-1},\xi_{\mathrm{std}})$ that are not contact iso…

Non-simplicity of formal contact isotopy classes of isocontact embeddings
Let $n$ be a positive integer, and let $(S^{2n+1},\xi_\text{st})$ be the standard contact sphere. Consider isocontact embeddings of $(\partial T^*S^n,\xi_\text{st})$ into…
