As a consequence, we prove that the $b$-adic expansion of a Liouville number cannot be generated by a finite automaton, a conjecture due to Shallit. %G English %2 https://hal.science/hal-00017758/document %2 https://hal.science/hal-00017758/file/Adamczewski_Cassaigne.pdf %L hal-00017758 %U https://hal.science/hal-00017758 %~ UNIV-ST-ETIENNE %~ CNRS %~ ICJ %~ UNIV-AMU %~ UNIV-LYON1 %~ INSA-LYON %~ EC-LYON %~ IML %~ I2M %~ INSA-GROUPE %~ UDL %~ UNIV-LYON
