DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OATS/19/">Mo
 del category structures and spectral sequences</a>\nby Sarah Whitehouse (S
 heffield) as part of Online algebraic topology seminar\n\n\nAbstract\nI'll
  discuss a family of model category structures such that weak equivalences
  are morphisms inducing an isomorphism at a fixed stage of a spectral sequ
 ence. The talk will focus on joint work with Xin Fu\, Ai Guan and Muriel L
 ivernet\, giving such model structures for multicomplexes. A multicomplex 
 (also known as a twisted chain complex) is an algebraic structure generali
 zing the notion of a chain complex and that of a bicomplex. These structur
 es have arisen in many different places and play an important role in homo
 logical and homotopical algebra.\n
