THE AZERBAIJANI SCIENCTIFIC COMMUNITY FACED HEAVY LOSS


 April 22, 2021

An outstanding scientist in the field of geomechanics, geodynamics and tectonophysics, the head of the department of tectonophysics and geomechanics of the ANAS Institute of Geology and Geophysics, honored scientist, academician Hatam Hidayat oglu Guliyev died on April 21, 2021 at the age of 74.

In 1969, Hatam Guliyev graduated from the mechanical-mathematical faculty of the Azerbaijan State University (now Baku State University) with a degree in Mechanics.
In 1972, H.Guliyev take degree of PhD in Physics and Mathematics, in 1981 - Doctor of physical-mathematical sciences, as well as the title of Professor in 1986, in 2001 became the corresponding member of ANAS, and in 2014 he was elected a full member of ANAS.

Since 1969, the scientist began to work at the Academy of Sciences of Azerbaijan and in different years held a number of positions. From 2003 to the end of his life he worked as the head of the department of tectonophysics and geomechanics of the ANAS Institute of Geology and Geophysics.

Under the leadership and the direct involvement of the scientist, the important scientific and technical projects were implemented by order of the worlds leading oil companies and a number of national organizations. His main scientific results consist of: creation of instability concept of evolution of the Earth and non-classical linearized approach to study this evolution; theoretical basis of mathematical-geodynamic model of development of internal structures of the Earth; mechanisms of formation of folding and fractures and their non-classical three-dimensional theory; exact solution of complete non-linear task of distribution of medium density in the Earths interior and proof of instability of this solution for different rocks; solving of problem of sequence of realization of deformation process and phase transitions depending on density; Development of differential geomechanical criteria of distribution of elastic and physical parameters on depth of the internal structures of the Earth; evidence of violations of these criteria in the solid core of the Earth; for the purpose of interpreting the data of observations on selfoscillations of the Earth, the solution of problem of selfoscillations of the three-layered sphere, elastic parameters which are not uniform in depth; nonlinear theories of multi-componential and three-dimensional seismic waves; creation of non-classical theoretical base model of seismicity; instability concept of destruction of rocks of the Earths interior; three-dimensional mathematical theory of loss of stability of equilibrium state in vicinities of wells, separate parts and internal structures of geological section; solution of nonlinear tasks on dynamics, mechanics of destruction, strength and stability of deformed solid bodies; development of paradigm of eternal cycle of matter; new definitions of matter concept, space and time; introduction of new concepts of free states and information form of matter into science; clarification of mechanism of unidirectionality of time flow and a number of important works on other scientific directions.

The scientific activity of academician H. Guliyev and his contribution to the development of Azerbaijani science were highly appreciated. The scientist was awarded a silver medal of Exhibition of Achievements of the National Economy of the USSR (1988), Decree of ANAS Presidium (2006 and 2016). He is honored scientist of the Republic of Azerbaijan (2018).

The memory of the famous scientist, academician Hatam Hidayat oglu Guliyev will forever remain in the hearts of those who know him.

Allah rehmet elesin!
