Query: On the homotopy exact sequence for log algebraic fundamental groups   We construct a log algebraic version of the homotopy sequence for a
quasi-projective normal crossing log variety over a log point of characteristic
zero and prove some exactness properties of it. Our proofs are purely
algebraic.
