DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geolis/168/"
 >Embeddings of more than 8 symplectic balls in $\\mathbb CP^2$</a>\nby Mar
 tin Pinsonnault (University of Western Ontario in London) as part of Geome
 tria em Lisboa (IST)\n\n\nAbstract\nWe prove that the space of symplectic 
 embeddings of $n\\geq 1$ standard balls\, each of capacity at most $\\frac
 {1}{n}$\, into the standard complex projective plane $\\mathbb CP^2$ is ho
 motopy equivalent to the configuration space of $n$ points in $\\mathbb CP
 ^2$. Our techniques also suggest that for every $n \\geq 9$\, there may ex
 ist infinitely many homotopy types of spaces of symplectic ball embeddings
