We prove that the set of all Bland preradical filters over an arbitrary differential ring form a quantale with respect to meets where the role of multiplication is played by the usual Gabriel pro-duct of filters. A subset of a differential pretorsion theory is a subquantale of this quantale. 2007-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/152385 On one-sided Lie nilpotent ideals of associative rings Luchko, V.S.; Petravchuk, A.P. We prove that a Lie nilpotent one-sided ideal of an associative ring R is contained in a Lie solvable two-sided ideal of R. An estimation of derived length of such Lie solvable ideal is obtained depending on the class of Lie nilpotency of the Lie nilpotent one-sided ideal of R. One-sided Lie nilpotent ideals contained in ideals generated by commutators of the form […[[r₁,r₂],…],rn₋₁],rn] are also studied.. 2007-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/152384 Discrete limit theorems for Estermann zeta-functions. I Laurincikas, A.; Macaitiene, R. A discrete limit theorem in the sense of weak convergence of probability measures on the complex plane for the Estermann zeta-function is obtained. The explicit form of the limit measure in this theorem is given. 2007-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/152383 On differential preradicals Horbachuk, O.; Komarnytskyi, M.; Maturin, Y. Differential preradicals and differential preradical filters are considered. Differentially closed fields are investigated. 2007-01-01T00:00:00Z
