|This is a work in progress joint with D. Panov.
Ramification of polyhedral space is defined as its
universal cover which branching in its singular set.
We conjecture that the ramification of polyhedral space
with nonnegative curvature has nonpositive curvature.
This conjecture is closely related to the questions on
complex hyperplane arrangements.
The conjecture proved two cases (A) 3D-case and (B) 4D-case
with complex structure.|
