DESCRIPTION:In addition to well-known adjoint/matrix model and vector mode
l large N limits\, a new large N limit dominated by melonic diagrams has a
ttracted a great deal of attention recently. The melonic limit was first o
bserved in tensor models\, but interest in this limit grew due in large pa
rt to its appearance in the SYK model. While there are important dynamical
differences between the SYK model and tensor models\, tensor models provi
de a very natural context for understanding the diagrammatics of the melon
ic large N limit\, and its possible generalizations.\n\nHere we seek to be
tter understand the entire range of models for which melonic diagrams domi
nate. We study tensor models constructed out of fields that are rank-r ten
sors with order-q interaction vertices. We define subchromatic tensor mode
ls to be those for which r \n\nhttps://indico.tifr.res.in/indico/conferenc
