Abstract
The paraconductivity along the ab-plane (sigma'(ab)) and c-axis (sigma'(c)) and fluctuation specific heat (Cn) Of layered superconductors with inequiv alent layers are calculated using a Lawrence-Doniach (LD) free energy funct ional proposed by Bulaevskii and Vagner [phys. Rev. B43, 8694 (1991)]. Dime nsional cross-over (DCR) occurs near T-c. The specific temperature dependen ce of sigma'(c) differs qualitatively from that of sigma'(ab).
