This field investigates the relationships and bounds between various function norms, particularly through inequalities that characterise the smoothness and approximability of functions, as well as the ...

Proceedings of the American Mathematical Society, Vol. 119, No. 3 (Nov., 1993), pp. 811-816 (6 pages) Given a closed subset F of either RN, N ≥ 3, or a Riemann surface, necessary and sufficient ...

We show that the absorption spectrum in semiconducting nanotubes can be determined using the bosonization technique combined with mean-field theory and a harmonic approximation. In this framework, a ...
