Query: Elliptic symbols, elliptic operators and Poincar\'e duality on conical
  pseudomanifolds   In a earlier work of Claire Debord and the author, a notion of noncommutative
tangent space isdefined for a conical pseudomanifold and the Poincar\'e duality
in $K$-theory is proved between this space and the pseudomanifold. The present
paper continues this work. We show that an appropriate and natural presentation
of the notion of symbols on a manifold generalizes right away to conical
pseudomanifolds and that it enables us to interpret the Poincar\'e duality in
the singular setting as a principal symbol map.
