Let f: S$\rightarrow$ C be a fiber space with connected fibers. We may have an information about a surface S from the fiber space structure. The result we have is ${\chi}({\mathcal O}_C){\chi}({\mathcal O}_F){\leq}{\chi}({\mathcal O}_S)$.

We compute the Jordan constant for the group of birational automorphisms of a projective plane ${\mathbb{P}}^2_{\mathbb{k}}$, where ${\mathbb{k}}$ is either an algebraically closed field of characteristic 0, or the field of real numbers, or the field of rational numbers.

Hepatitis B virus (HBV)is a member of the Hepadna virus family whose members share a characteristic virion structure and genome size, around 3.2kb in a paritially double-stranded form. The genome of HBV contains four overlapping open reading frames designated as P(polymerase). C(core), S(surface antigen)and X. The X gene has potential to encode 154 amino acids protein.
