Abstract
We have used a q-space method for calculating thermodynamic quantities of a two-dimensional vesicle introduced by Ostrowsky
and Peyraud. This method has been used to calculate the radius of gyration, the area, and the shape of vesicles as a function
of perimeter length
and Helfrich curvature parameter
K. It is found, in agreement with the hypothesis of Fisher, that all thermodynamic quantities can be plotted on universal curves
as a function of
. In the small
, large
K (stiff), and large
, small
K (floppy or fractal) limits, the results are broadly consistent with real space computations of other authors.
