Moderately non-local $$\eta {\bar{\eta }}$$ η η ¯ vertices in the $$AdS_4$$ A d S 4 higher-spin gauge theory
Abstract A new concept of moderate non-locality in higher-spin gauge theory is introduced. Based on the recently proposed differential homotopy approach, a moderately non-local scheme, that is softer than those resulting from the shifted homotopy approach available in the literature so far, is worke...
