We also give a new example with called Cohen p-nuclear and factorable strongly p-nuclear two Lipschitz operator’s idealsenLipschitz operators, bilinear operators, tensor product, Arens-Eells space, linear operator ideals, multi-linear operator ideals, Lipschitz operator ideals, p-nuclear operators, Cohen p nuclear operators .Thesis
