_version_	1866929544465743872
author	Calaque, Damien
author_facet	Calaque, Damien
contents	This short paper illustrates the general framework introduced in the paper "Not too little discs" (arXiv:2407.18192), joint with Victor Carmona, on yet another one dimensional example. It exhibits a discrete model for the free scalar field on the real line, adapting the treatment from the book of Costello--Gwilliam to the discrete setting.
