Query: On hyperlogarithms and Feynman integrals with divergences and many
  scales   It was observed that hyperlogarithms provide a tool to carry out Feynman
integrals. So far, this method has been applied successfully to finite
single-scale processes. However, it can be employed in more general situations.
We give examples of integrations of three- and four-point integrals in
Schwinger parameters with non-trivial kinematic dependence, involving setups
with off-shell external momenta and differently massive internal propagators.
The full set of Feynman graphs admissible to parametric integration is not yet
understood and we discuss some counterexamples to the crucial property of
linear reducibility. Furthermore we clarify how divergent integrals can be
approached in dimensional regularization with this algorithm.
