Abstract: | This study focuses on the anisotropic Besov-Lions type spaces B
p,θ
l
(Ω;E
0,E) associated with Banach spaces E
0 and E. Under certain conditions, depending on l = (l
1, l
2,⋯, l
n
) and α = (α1, α2, ⋯, α
n
), the most regular class of interpolation space E
α between E
0 and E are found so that the mixed differential operators D
α are bounded and compact from B
p,θ
l+s
(Ω;E
0,E) to B
p,θ
s
(Ω;E
α). These results are applied to concrete vector-valued function spaces and to anisotropic differential-operator equations
with parameters to obtain conditions that guarantee the uniform B separability with respect to these parameters. By these results the maximal B-regularity for parabolic Cauchy problem is obtained. These results are also applied to infinite systems of the quasi-elliptic
partial differential equations and parabolic Cauchy problems with parameters to obtain sufficient conditions that ensure the
same properties.
