added pointer to these two recent references, identifying further $L_\infty$-algebra structure in Feynman amplitudes/S-matrices of perturbative quantum field theory:

• Markus B. Fröb, Anomalies in time-ordered products and applications to the BV-BRST formulation of quantum gauge theories (arXiv:1803.10235)

• Alex Arvanitakis, The $L_\infty$-algebra of the S-matrix (arXiv:1903.05643)

Hm, this entry I had clearly created to be !included as the References-section at L-∞ algebra. But now I saw that there was no such !include, instead just a literal copy of the conyent. I am !incudeing it now, hoping that I am not breaking something thereby.
