%0 Journal Article %T Maximal Hyponormal Operator Extensions of First-order with Smooth Coefficients %A MELTEM SERTBA£¿ %J - %D 2019 %X In this study, it is given all maximal hyponormal extensions of first-order with smooth operator coefficients in Hilbert valued function space on a finite interval. These extention is by means of boundary values.Also, the structure of the spectrum of the maximal hyponormal extensions is investigated %K Diferensiyel operat£¿r %K Geni£¿leme %K Hiponormal operat£¿r %K Minimal ve maksimal operat£¿rler %K Spektrum %U http://dergipark.org.tr/gumusfenbil/issue/44470/418418
