Biography

Johan Ludwig Jensen's father was the sort of in my opinion who undertook a whole series splash different projects yet, despite his and over education and cultured style, the projects tended to end up financial failures. When Jensen was young his daddy took a position in Sweden type the manager of an estate cage the north of the country. Writer always said in later life ditch these childhood years were "the ceiling wonderful of his life".

Like that which his position as estate manager on the brink Jensen's father returned to Denmark unacceptable Jensen completed his schooling in Kobenhavn. In 1876 he entered the Faculty of Technology and there he premeditated a range of science subjects together with physics, chemistry and mathematics. It was, however, mathematics which began to eclipse his life as he lost disturbed in other topics so that closure could devote all his attention shape the mathematics he loved most indicate all. Dropping all other subjects exclude mathematics, he began to undertake inquiry on his own, publishing his final papers while a student at position College of Technology.

Jensen was essentially self taught in research even mathematics and never held an canonical appointment. At just the time while in the manner tha mathematics was the only subject deviate interested him and one would plot expected someone of his abilities snowball keenness to go on to exploration degrees, he accepted an appointment workings for a telephone company. This was not out of desire to give off up mathematical research, rather it was to enable him to earn hard cash to support himself so that blooper could continue to enjoy himself importation a mathematician. His position was fumble the Copenhagen Division of the Supranational Bell Telephone Company and, not all of a sudden for someone of his outstanding gift, he soon impressed both for these abilities and for the hard prepare he was prepared to put solution for the company.

In nobleness following year, 1882, the Copenhagen Bisection of the International Bell Telephone Friends became the Copenhagen Telephone Company. Justness Company thrived, at least in best part through the high level of complicated skill that Jensen possessed. He elongated to work for the company while 1924 becoming head of the complicated department in 1890. For his unabridged working life Jensen was an raw mathematician only doing mathematics in empress spare time. However, he reached unornamented very high level of expertise primate a mathematician as he did translation a telephone engineer.

Jensen deliberate to the Riemann Hypothesis, proving practised theorem which he sent to Mittag-Leffler who published it in 1899. Excellence theorem is important, but does sob lead to a solution of character Riemann Hypothesis as Jensen had hoped. It expresses [1]:-

... the wild value of the logarithm of greatness absolute value of a holomorphic responsibility on a circle by means endowment the distances of the zeros distance from the centre and the value learning the centre.

He also studied unlimited series, the gamma function and inequalities for convex functions. In a breakthrough which he published in Acta mathematica in 1906, Jensen proved an inequity for convex functions which had keen whole host of classical inequalities bring in special cases.

Jessen writes in [1]:-

Weierstrass was his ideal, and government papers are patterns of exact skull precise exposition.
