Let g be any untwisted affine Kac–Moody algebra, μ any fixed complex number, and g˜(μ) the corresponding toroidal extended affine Lie algebra of nullity two. For any k-tuple λ=(λ 1,⋯, λ k) of weights of g, and k-tuple a=(a 1,⋯, a k) of distinct non-zero complex numbers, we construct a class of modules V˜(λ, a) for the extended affine Lie algebra g˜(μ). We prove that the g˜(μ)-module V˜(λ, a) is completely reducible. We also prove that the g˜(μ)-module V˜(λ, a) is integrable when all weights λ i in λ are dominant. Thus, we obtain a new class of irreducible integrable weight modules for the toroidal extended affine Lie algebra g˜(μ).
