DESCRIPTION:The Witt complex of a scheme can be thought of as the negative
  degree part of Gersten complexes for Milnor-Witt K-theory. Depending on t
 he data of a residual complex\, we will describe generalisations of the cl
 assical second residue homormophism for Witt groups - which are the protot
 ype for the boundary maps appearing in the Witt complex. We&#39\;ll sketch
  why our residue homomorphisms assemble to form a Witt complex - even in c
 haracteristic 2 - with a focus on understanding the similarities between o
 ur construction and Balmer&#39\;s  <br><br><br><br><br>
