Mathematical analysis

(mathematicalanalysis)






Analysis is that branch of mathematics which deals with the real numbers and complex numbers and their functions . It has its beginnings in the rigorous formulation of calculus and studies concepts such as continuity , integration and differentiability in general settings.

History

Historically, analysis originated in the 17th century , with theinvention of calculus by Newton and Leibniz . In the 17th and 18th centuries ,analysis topics such as the calculus of variations , differential and partial differential equations , Fourier analysis and generating functions were developed mostly in applied work. Calculus techniques were appliedsuccessfully to approximate discrete problems by continuous ones.

All through the 18th century the definition of the concept function was a subject of debate among mathematicians. In the 19th century , Cauchy was the first toput calculus on a firm logical foundation by introducing the concept of Cauchy sequence . He also started the formal theory of complex analysis . Poisson , Liouville , Fourier and others studied partial differential equations and harmonic analysis .

In the middle of the century Riemann introduced his theory of integration . The last third of the 19th century saw the arithmetization ofanalysis by Weierstrass , who thought that geometric reasoning wasinherently misleading, and introduced the ε-δ definition of limit . Then,mathematicians started worrying that they were assuming the existence of a continuum of real numbers without proof. Dedekind then constructed the real numbers by Dedekind cuts . Around that time, the attempts to refine the theorems of Riemann integration led to the study of the "size" of the discontinuity sets ofreal functions.

Also, " monsters " ( nowhere continuous functions, continuous but nowhere differentiablefunctions, space-filling curves ) began to be created. In thiscontext, Jordan developed his theory of measure , Cantor developed what is now called na´ve set theory , and Baire proved the Baire category theorem . In the early 20th century , calculus was formalized using axiomatic set theory . Lebesgue solved the problem of measure, and Hilbert introduced Hilbert space to solve integral equations . The idea of normed vector space was in the air, and in the 1920s Banach created functional analysis .
