# The algebra of cell-zeta values

@article{Brown2010TheAO, title={The algebra of cell-zeta values}, author={Francis Brown and Sarah Carr and Leila Schneps}, journal={Compositio Mathematica}, year={2010}, volume={146}, pages={731 - 771} }

Abstract In this paper, we introduce cell-forms on π0,n, which are top-dimensional differential forms diverging along the boundary of exactly one cell (connected component) of the real moduli space π0,n(β). We show that the cell-forms generate the top-dimensional cohomology group of π0,n, so that there is a natural duality between cells and cell-forms. In the heart of the paper, we determine an explicit basis for the subspace of differential forms which converge along a given cell X. Theβ¦Β Expand
