MV-frames
Jean B Nganou
Complete MV-algebras are naturally equipped with frame structures. We call them MV-frames and investigate some of their main the properties as frames. We completely characterized a…
Compact Hausdorff MV-algebras: Structure, Duality and Projectivity
Jean B. Nganou
It is proved that the category of extended multisets is dually equivalent to the category of compact Hausdorff MV-algebras with continuous homomorphis…
Stone MV-algebras and Strongly complete MV-algebras
Jean B. Nganou
Compact Hausdorff topological MV-algebras and Stone MV-algebras are completely characterized. We obtain that compact Hausdorff topological MV-algebras are product (both topological…
On the Chang's group of BL-algebras
Jean B. Nganou, Celestin Lele
For an arbitrary BL-algebra L, we construct an associated lattice Abelian group that coincides with Chang's group when the BL-algebra is an MV-algebra. We prove that the Chang's gr…
On the Dec group of finite abelian Galois extensions over global fields
Jean B Nganou
If K/F is a finite abelian Galois extension of global fields whose Galois group has exponent t, we prove that there exists a short exact sequence that has as a consequence that if…
