Abstract: We study the heavy-quark contributions to the proton structure function F2(x,Q2) at next-to-leading order using compact formulas at small values of Bjorken's x variable. The formulas provide a good agreement with the modern HERA data for F2c(x,Q2).<br />Comment: 8 pages, 1 figure, presented on the XIV International Conference on Symmetry Methods in Physics (SYMPHYS-XIV), Tsakhkadzor, Armenia, August 16 - 22, 2010
