Aceasta este cartea clasica a analizei convexe, accesibila atat celor cu o cultura matematica solida cat si celor interesati doar de anumite aspecte ale teoriei functiilor si multimilor convexe. Considerata inca de la prima aparitie din 1970 ca fiind cartea fundamentala in analiza convexa, retiparita de foarte multe ori si utilizata de generatii de studenti, matematicieni, ingineri, economisti precum si de toti cei interesati de probleme de optimizare, aceasta carte si-a pastrat in intregime actualitatea si utilitatea.
Avand in vedere ca este adresata unui auditoriu divers, autorul a pastrat expunerea la un nivel relativ elementar prin restrangerea la cazul finit dimensional. Cititorul care este interesat si de alte aspecte ale teoriei functiilor convexe pe spatii vectoriale topologice va gasi in aceasta carte un binevenit punct de pornire. Cele opt capitole ale cartii sunt precedate de un ghid de orientare, indicand care anume rezultate sunt esentiale la o prima citire.
Teoria prezentata in aceasta carte este aplicata cu un deosebit succes in matematici financiare.
