The subject of this work is the study of local dynamics of full-coupled chains of a great number of oscillators with a large delay in couplings. From a discrete model describing the dynamics of a great number of coupled oscillators. a transition has been made to a nonlinear integro-differential equation. continuously depending on time and space variable. https://safeersappliancers.shop/product-category/neff-u2acm7hn0b-n50-built-in-59cm-a-b-electric-double-oven-stainless-steel/
