Generalized gegenbauer shift and some problems of the theory of approximation of functions on the metric of L2,?
(Institute of Mathematics and Mechanics, National Academy of Sciences of Azerbaijan, 2015)
In this paper we consider some problems of the theory of approximation of functions on interval [0, ?) in the metric of L2,? with weight sh2?x. The modulus of continuity used in those problems is constructed with the help ...

Synthesis, molecular conformation, vibrational, electronic transition, and chemical shift assignments of 4-(thiophene-3-ylmethoxy)phthalonitrile: a combined experimental and theoretical analysis
(SPRINGER/PLENUM PUBLISHERS, 2011)
This work presents the synthesis and characterization of a novel compound, 4-(thiophene-3-ylmethoxy)phthalonitrile (TMP). The spectroscopic properties of the compound were examined by FT-IR, FT-Raman, NMR, and UV techniques. ...
The boundedness of the generalized anisotropic potentials with rough kernels in the Lorentz spaces
(TAYLOR & FRANCIS LTD, 2011)
In this paper, we study the generalized anisotropic potential integral K(alpha,gamma) circle times f and anisotropic fractional integral I(Omega,alpha,gamma) f with rough kernels, associated with the Laplace-Bessel ...
The new upper bounds on the spectral radius of weighted graphs
(ELSEVIER SCIENCE INC, 2012)
Let us consider weighted graphs, where the weights of the edges are positive definite matrices. The eigenvalues of a weighted graph are the eigenvalues of its adjacency matrix and the spectral radius of a weighted graph ...
P(X)-admissible sublinear singular operators in the generalized variable exponent morrey spaces
(Institute of Mathematics and Mechanics, National Academy of Sciences of Azerbaijan, 2016)
In this paper we prove the boundedness of the p(x)-admissible sublinear singular operators on generalized Morrey spaces Mp(·),? (Rn) with variable exponent. © 2016, Institute of Mathematics and Mechanics, National Academy ...
ALMOST UNIT-CLEAN RINGS
(EDITURA ACAD ROMANE, 2019)
A ring R is almost unit-clean provided that every element in R is equivalent to the sum of an idempotent and a regular element. We prove that every ring in which every zero-divisor is strongly pi-regular is almost unit-clean ...
The effect of strain relaxation on electron transport in undoped Al0.25Ga0.75N/GaN heterostructures
(ELSEVIER SCIENCE BV, 2007)
The two-dimensional electron gas (2DEG) transport properties of two-step growth undoped Al0.25Ga0.75N/GaN heterostructures with semi-insulating buffer, grown by MOCVD, were investigated in a temperature range of 20-350K. ...
A versatile study of novel A3B-type unsymmetric zinc(II) phthalocyanines containing thiazolidin-4-one: Their, carbonic anhydrase I, II isoenzymes, and xanthine oxidase inhibitors evaluation
