Nx. Chen et Eq. Rong, UNIFIED SOLUTION OF THE INVERSE CAPACITY PROBLEM, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 57(2), 1998, pp. 1302-1308
The inverse specific hear problem has played a significant role in phy
sics. But there is no satisfactory solution for this inherently ill-po
sed inverse problem. The present work shows a concise and unified solu
tion based on the Mobius inversion technique and the Poisson-Abel proc
ess. This solution can explain both Debye's and Einstein's approximati
ons very well. All the mathematical deductions are shown in the Append
ixes; they are deduced in an elementary way for physicists. [S1063-651
