Abstract: In the present study, the abstract approach for solutions of partial differential
 equations in the modeling of
 processes of engineering  and technology. Various local and nonlocal problems for partial differential equations can be
reduced to local and nonlocal  problems for ordinary differential equations in Banach spaces with unbounded positive
operator. The boundness of functions of some positive operators is considered.

Bionote – Prof. Dr. Allaberen Ashyralyev

Prof. Dr.  Ashyralyev was born in Konekesir/Turkmenistan in 1955. He completed his a high school education in 1972 in Konekesir with a gold medal for excellence at Secondary School Level. He graduated from the Turkmen State University in 1977. He was awarded with the Lenin’s Grant for Students during his education (1974-1977).

He earned his PhD from the Voronezh State University in 1983, and his Doctorate of Sciences from the same University and the Institute of Mathematics of the Ukraine Academy of Sciences in 1992. Ashyralyev had been awarded the First Rank Prize for PhD students upon his graduation in 1983. Dr. Ashyralyev was a visiting scholar at the Voronezh State University, Russia, in 1979, 1985, 1991 and University of California, Santa Barbara, USA, in 1987-1988.Dr. Ashyralyev continued his career at the Turkmen State University from 1977 to 1999 as an Instructor, assistant professor (1985), associate professor (1989), and professor (1995), respectively. In 1996 Ashyralyev had been awarded the entitled
Master Teacher of Turkmenistan by Ministry of Education, Turkmenistan.

Since September 01, 1999 to May 30, 2016, Prof. Ashyralyev has been a staff member of the Department of Mathematics and Elementary Mathematics Education, Fatih University, Turkey and visiting professor at the Intenational TTU,Turkmenistan. Since May 15, 2015 Prof. Ashyralyev has been a visiting Professor, Institute of Mathematics and Mathematical Modeling, Almaty, Kazakhstan and since April 01, 2017 visiting professor at the Peoples' Friendship University of Russia (RUDN), Russia. Since September 20, 2016 to September 22, 2021, Prof. Ashyralyev has been a staff member of the Department of Mathematics, Near East University in Cyprus. Since the Spring of 2018, to September 22, 2021, he has been the Head of Department of Mathematics Education at the Atatürk Education Faculty. Since November 17, 2021 Prof. Ashyralyev has been a staff member of the Department of Mathematics, Bahcesehir University in Istanbul.

The research interests of A. Ashyralyev are broad and include different problems of numerical functional analysis, well-posedness of differential and difference problems, construction and investigation of high order of accuracy difference schemes for partial differential equations, uniform difference schemes and asymptotic formulas for singular perturbation problems for partial differential equations, study of positivity of differential and  difference operators  and  structure  of  fractional  spaces  generated  by  positive  differential  and  difference operators  in  Banach  spaces, investigation  of  difference  schemes  for  stochastic  partial  differential  equations,  study  of  identification  problems,  fractional  calculus,  and
 mathematical modeling.
