  The synthetic EHP sequence

  The lower central series spectral sequence is a particular form of unstable Adams spectral sequence defined by Curtis in 1963. I will describe a categorification of this spectral sequence, which gives a category of 'synthetic spaces' interpolating between pointed connected spaces and restricted Lie algebras. An appealing feature is the existence of an EHP sequence in this setting; this can be used to study the classical EHP spectral sequence using Curtis' (far more computable) algebraic EHP spectral sequence.

If you have any questions, please contact Toni Annala, Nikolai Konovalov, Akhil Mathew, Tomer Schlank, or Peter May.
