“…Recall that, if p 0 , p 1 , p , λ 0 , λ 1 , λ are constants with and , then is the closure of in and . - 3.If and and are variable exponents, then our result is related to the complex interpolation of variable Lebesgue spaces, previously obtained in [6] (see also [7, 14]). In fact, Theorem 1.1 recaptures the results in [6].
