This work is devoted to the hyperbolic equation of heat conduction
and the relaxation equation of heat conduction derived by the author.
The hyperbolic equation of heat conduction can be considered as a special
case of the more general relaxation equation of heat conduction
which takes into account the relaxation of heat flux (the finite speed
of heat flux propagation) and the relaxation of internal heat
source capacity. The work is devided into four parts. The first chapter
includes an introduction to the mathematical modelling of heat conduction
in solids. The second chapter is focused on the formulation and features
of the parabolic, hyperbolic and relaxation models of heat conduction.
In the third chapter, selected cases of the hyperbolic heat
conduction are solved by analytical and numerical methods. In the fourth
chapter, the author solves a number of __relaxation__ initial and boundary
value problems using analytical, semi-analytical and numerical methods.

Most of the original solutions presented in the work have been previously
published in the leading international journals, such us: International
