comment Questions on Discrete Exterior Calculus in numerial computing
@Artur Palha:Thanks!I am working on numerically solve equations in fluid mechanics, elasticity and electromagnetism using DEC, and develop software for this, however, it seems that the solution is still not completely found. What's your opinion?Thanks!

comment Why is this a local constant sheaf
@Emerton, thanks!but how can we see the action of $G$ on $V$ from this local system? If we choose a point $x$ in $M$,do we get a section $c\in V$ of this local system over the point $[x]$ in $M/G$?And then if we choose another point $y$ which in the same orbit of $x$,assume $yg=x$,then we get another section $c'\in V$ over $[y]=[x]$,is that $gc=c'$?

comment homotopy invariant and coinvariant
@Sinha, Could you explain why taking equivariant homomorphisms from chains on $S^\inf_{+}$ to a given $V$ yields $V[[t]]$? Thanks!
