Evariste Galois, 1811-1832 (Matematica Sulle Barricate)

It took more than seventy years to fully understand the French mathematician's first memoire (published in 1846) which formulated the famous 'Galois theory' concerning the solvability of algebraic equations by radicals, from which group theory would follow. Obscurities in his other writings - memoires and numerous fragments of extant papers - persist and his ideas challenge mathematicians to this day. Thus scholars will welcome those chapters devoted specifically to explicating all aspects of Galois' work.
