In the study of system (1) in Chisinau, are ductive Lie algebra L9 was used to represent the centro-afinegroup GL(3,R) in the space of the coefficients of this system.
Two parameter singular perturbation problems for sine-Gordon type equations

PERJAN, Andrei; RUSU, Galina (Technical University of Moldova, 2021)

We obtain some a priori estimates of solutions to the perturbed problem, which are uniform with respect to parameters, and a relationship between solutions to both problems. We establish that the solution to the unperturbed ...
State of infosecurity in the Republic of Moldova

BOLUN, Ion; CIORBA, Dumitru; BULAI, Rodica; CALIN, Rostislav; BODOGA, Cristina (Technical University of Moldova, 2021)
