Abel, Niels Henrik (1802-29), Norwegian mathematician,
who was the first to demonstrate conclusively the
impossibility of solving by the elementary processes
of algebra general equations of any degree higher than the fourth.
Abel was born on Finn鴜a
Island, Rogaland County. After study at the
University of Christiania (now Oslo), he spent two years in Paris
and Berlin and in 1828 was made instructor
at the university and military school in Christiania.
His chief contributions were to the theory of
functions, of which he was a founder. An important
class of transcendental functions is known as Abelian,
after their discoverer, as are Abelian equations,
groups, and bodies. The binomial theorem had been
formulated by Sir Isaac Newton and the Swiss
mathematician Leonhard Euler, but Abel gave
it a more comprehensive generalization,
including the cases of irrational and
imaginary exponents.
