## Abstract Let __X__ be a Banach space. We show that each __m__ : โ \ {0} โ __L__ (__X__ ) satisfying the Mikhlin condition sup~__x__ โ 0~(โ__m__ (__x__ )โ + โ__xm__ โฒ(__x__ )โ) < โ defines a Fourier multiplier on __B__ ^__s__^ ~__p,q__~ (โ; __X__ ) if and only if 1 < __p__ < โ and __X__ is isomorp

## Abstract The aim of this note is to study the spectral properties of the LUECKE's class __R__ of operators __T__ such that โ(__T โ zI__)^โ1^โ=1/__d__(__z, W__(__T__)) for all __z__โ__CLW__(__T__), where __CLW__(__T__) is the closure of the numerical range __W__(__T__) of __T__ and __d__(__z, W__
