# Synopsis top ↑

In the present book new methods are discussed, by which the
distribution of resistivity layers in the subsurface can be
determined directly from the results of resistivity measurements.
The contribution of the present author is restricted to the derivation
of a practical procedure of determining the kernel function from the
resistivity measurements.

The book has been written on two different levels at the same
time. Readers, who wish to make themselves familiar with the practical
interpretation technique without fully understanding the theoretical
background of it, may omit the chapters 1 to 5 and 7 to 8. The
remaining chapters form a closed unit, which can be understood with
only elementary knowledge of algebra and of differential calculus. To
understand the whole book, a good knowledge of differential and of
integral calculus is required. No advanced knowledge is needed,
however, of special subjects, in particular of the theory of
determinants and of the theory of BESSEL functions. Both these
subjects are essential to the interpretation of resistivity
measurements, but the properties of determinants and of BESSEL
functions are treated in the present book itself, to the extent that
is required for understanding the interpretation methods of
resistivitv measurements.
