Generating trees growing on the left for pattern-avoiding inversion sequences
Benjamin Testart
This work concerns a construction of pattern-avoiding inversion sequences from right to left we call the generating tree growing on the left. We first apply this construction to in…

Completing the enumeration of inversion sequences avoiding one or two patterns of length 3
Benjamin Testart
We present four constructions of inversion sequences, and use them to compute the enumeration sequences of 24 classes of pattern-avoiding inversion sequences. This completes the en…
