Three general plane conics admit complex tangent circles, and it had been conjectured that at most of them could be real. We construct an explicit strongly general trip…

Adjacent non-stable layers in the -homotopy of the special linear tower
Haoyang Liu, Fan Yang
We determine the two cross-stage morphisms arising from adjacent Stiefel fiber sequences in the special linear tower. Over characteristic-zero fields, the first is the Wood morphis…
