The thesis is devoted to general theory of extensions of arbitrary topological spaces, which is an important and still developing domain of topology. The general conception, examined in the work, allows to obtain the new results in the class of completely regular spaces, too. AII hypothesized topological spaces are assumed to be То-spaces in case we have no concrete indications. In the work are solved the following problems:
In the thesis are utilized the method of filters, the method of ideals, funcţional methods, the methods of the lattice theory. Some problems formulated by P. S. Alexandroff, A. V. Arhangel'skii, M. M. Cioban and L. D. Nel are solved.
The main results of the work can be applied in the studying of extensions and mappings, in theory of funcţional spaces, in the theory of ideals and in a course on extensions of topological spaces.
A bibliography of about 219 items is included. The thesis is written in Romanian.
