| Abstract | The multiplication operator Mu f=u.f within the bicomplex Lorentz space L(p,q)BC( ,M, ) is investigated. It is initially established that Mu is D-bounded if and only if the function u is essentially D-bounded. Subsequently, it is proved that the collection of all D-bounded multiplication operators on BC-Lorentz spaces forms a maximal abelian sub-algebra within the Banach algebra of all bounded linear operators on L(p,q)BC ( ,M, ). Additionally, a necessary and sufficient condition for the compactness of Mu is provided. Finally, by introducing a condition for a multiplication operator to exhibit a closed range, the author identifies some conditions equivalent to Mu being a Fredholm operator. |
