%0 Journal Article %T On Bounded Linear Operations in b-Hilbert Spaces and their Numerical Ranges %A Firoozeh Hasanvand %A Mahnaz Khanehgir %J Asian Journal of Fuzzy and Applied Mathematics %D 2015 %X In this paper, we introduce the notions of b-bounded linear operator, b-numericalrange and b-numerical radius in a b-Hilbert space and describe some of their properties. Thenwe will show that this new numerical range (radius) can be considered as a usual numericalrange (radius) in a Hilbert space, so it shares many useful properties with numerical range(radius) %K [bounded linear operator %K b-Hilbert space %K 2-inner product space %K 2-normed space %K numerical range %K numerical radius.] %U https://www.ajouronline.com/index.php/AJFAM/article/view/2875
