English
For each p with 1 ≤ p, the family fourier n defines elements of Lp(ℂ, p) on AddCircle(T); the function fourier n considered as an Lp function coincides a.e. with the pointwise monomial.
Русский
Для каждого p с 1 ≤ p мономии fourier n образуют элементы Lp(ℂ, p) на AddCircle(T); функция fourier n как элемент Lp равна почти повсеместно самой мономиале.
