1. Ward identity violation for melonic T 4 -truncation / Lahoche, Vincent ; Ousmane Samary, Dine
Referring to recent works concerning the functional renormalization group for tensorial group fields theories (Lahoche and Ousmane Samary (2018) [2] and [1] ), this paper gives in-depth explanation for, the ambiguity around the search of fixed points in the Wetterich flow equation and the Ward–Takahashi identities.

2. Nonperturbative renormalization group beyond the melonic sector: The effective vertex expansion method for group fields theories / Lahoche, Vincent ; Ousmane Samary, Dine
Tensor models admit the large N limit dominated by the graphs called melons. [...]
