Local properties of modules
 Lysoněk, Tomáš ; Hrbek, Michal (advisor) ; Příhoda, Pavel (referee)
This thesis introduces module properties of projectivity and flatness relative to classes of finitely presented modules, these being generalization of projectivity and pure pro- jectivity. Then it gives proof of ascent and descent of these properties through non- commutative ring homomorphisms with certain properties, most importantly reflection of pure epimorphisms. For relative case ascent and descent through flat ring homomor- phisms, which reflect pure epimorphisms, is given. Finally, these results are applied in the setting of homomorphisms arising as central extensions of pure and faithfully flat central ring homomorphisms. 1
