New characterizations of Lorentz spaces.
We derive new formulae that provide equivalent quasi-norms on Lorentz spaces.

Are generalized Lorentz ``spaces'' really spaces?
We show that the classical Lorentz space need not be a linear set for certain weights. We establish necessary and sufficient conditions or this situation to occur....

Normability of Lorentz spaces-an alternative approach
We study normability properties of classical Lorentz spaces. Given certain for it's associate space to be a Banach function space. We use this result to get an alternative proof of the Sawyer's characterization of ...

Optimality of embeddings of Bessel-potential-type spaces
Sharpness and non-compactness of embedding theorems for Bessel-potential spaces modelled upon Lorentz-Karamata spaces are presented. Target spaces are Lorentz-Karamata spaces and generalised Hölde...

Interpolation theorems for Block-Lorentz spaces
We show that the assumption $1/q = (1-/.theta.)/q_0 + /.theta./q_1$ is essential in the Asekritova-Krugljak-Maligranda-Nikolova-Persson theorem, and prove an interpolation theorem on weighted Lorentz spaces....

Characterization of associate spaces of generalized weighted weak-Lorentz spaces and embeddings
We characterize associate spaces of generalized weighted weak-Lorentz spaces and use this characterization to study embeddings between these spaces....

Concentration-Compactness Principle for Moser-type Inequalities in Lorentz-Sobolev Spaces
We obtain sharp constants concerning the Concentration compactness principle for Moser-type inequalities in Lorentz-Sobolev spaces. The results deal with the standard Lorentz quasinorm....

Characterization of associate spaces of weighted Lorentz spaces with applications
We characterize the associate spaces of weighted Lorentz spaces and present some applications of this result including necessary and sufficient conditions for a~Sobolev-type embedding....
