 From page 137...... He spent most of his working life in China cluring some of that country's most turbulent political upheavals. If many Chinese mathematicians nowadays are making clistinguishecl contributions at the frontiers of science en cl if mathematics in China enjoys high popularity in public esteem, that is clue in large measure to the leaclership Hua gave his country, as scholar en cl teacher, for 50 years.

This encouraged Harcly en cl Littlewoocl in 1920 to apply a similar method for general k, and they devised the so-callecl circle method to tackle the general Hilbert-Waring Read the entire page → From page 141......

One such average result, now known as Hua's lemma, asserts that for any £ > 0 en c! Read the entire page → From page 143...... him when later he reached a position of authority in the new China. In the years ahead, even though Hua's scientific activities branched out in other directions, Hua was always really to return to Waring's problem, to number theory in general en cl especially to questions involving exponential sums, thus as late as 1959 he publisher!

Harmonic Analysis of Functions of Several Complex Variables in the Classical Domains came out in 1958 and was translatecl into Russian in the same year, followocl by an English translation by the American Mathematical Society in 1963. Most of the results of this important monograph are clue to Hua, with some overlap with the work of Siegel. Read the entire page → From page 148...... Whether in ad hoc problemsolving sessions in factories or open-air teachings, he touched his audiences with the spirit of mathematics to such an extent that he became a national hero and even earned an unsolicitecl letter of commendation from Mao, this last a valuable protection in uncertain times.
