Lidskiǐ, in 1959, proved his famous theorem on the coincidence of the trace of the S1-operator in L2(ν) with its spectral trace ∑∞ k=1 μk(T). We show that for p ∈ [1, ∞] and s ∈ (0, 1] with 1/s = 1 + |1/2 - 1/p|, and for every s-nuclear operator T in every subspace of any Lp(ν)-space the trace of T is well defined and equals the sum of all eigenvalues of T.
