title={On Artin algebras arising from Morita contexts},
abstractNote={We study Morita rings Λ_(ϕ,ψ)=(smallmatrix A
&_AN_B_BM_A & B smallmatrix) in the context of Artin algebras from
various perspectives. First we study covariant finite, contravariant finite,
and functorially finite subcategories of the module category of a Morita ring
when the bimodule homomorphisms ϕ and ψ are zero. Further we give
bounds for the global dimension of a Morita ring Λ_(0,0), regarded as
an Artin algebra, in terms of the global dimensions of A and B in the case
when both ϕ and ψ are zero. We illustrate our bounds with some
examples. Finally we investigate when a Morita ring is a Gorenstein Artin
algebra and then we determine all the Gorenstein-projective modules over the
Morita ring with A=N=M=B=Λ, where Λ is an Artin algebra.},
