Abstract: Consecutive substitution reactions of arsenic(III)chloride with sodium salts of various oximes and morpholinedithiocarbamate (morphdtc) were carried out in 1:2:1 stoichiometry to obtain six new arsenic(III) mixed derivatives of the type: [(R)(R1)C = NO]2Sb[S2CN(CH2CH2)2O] [where R is –C6H5,… read more here.

DOI: 10.1080/00207160.2017.1381336
Abstract: ABSTRACT We present second-order difference schemes for a class of parabolic problems with variable coefficients and mixed derivatives. The solvability, stability and convergence of the schemes are rigorously analysed by the discrete energy method. Using… read more here.

DOI: 10.3390/sym14061225
Abstract: : Singular systems play an important role in many fields, and some new fractional operators, which are general, have been proposed recently. Therefore, singular systems on the basis of the mixed derivatives including the integer… read more here.
