On the controllability of a singular nonregular methaniser system
Scientific Reports, 2023 The control and command of singular systems of non-regular type pose very complex problems for automation engineers. The classic concepts of controllability are not applicable because of the non-regularity of the response of such systems whose internal ...

Jackson’s inequality in the complex plane and the Łojasiewicz–Siciak inequality of Green’s function
Journal of Approximation Theory, 2016 We prove a generalization of Dunham Jackson's famous approximation inequality to the case of compact sets in the complex plane admitting both upper and lower bounds for their Green's functions, i.e. the well known Holder Continuity Property (HCP) and the less known but crucial Lojasiewicz-Siciak inequality (LS).

Eigenvalue bounds of the shift-splitting preconditioned singular nonsymmetric saddle-point matrices
Journal of Inequalities and Applications, 2016 For singular nonsymmetric saddle-point problems, a shift-splitting preconditioner was studied in (Appl. Math. Comput. 269:947-955, 2015). To further show the efficiency of the shift-splitting preconditioner, we provide eigenvalue bounds for the nonzero ...

S. N. Bernstein Type Estimations in the Mean on the Curves in a Complex Plane
Abstract and Applied Analysis, 2009 The present paper discusses in the metric Lp S. N. Bernstein type inequalities of the most general kind on very general accessible classes of curves in a complex plane. The obtained estimations, generally speaking, are not improvable.

Some differential inequalities in the complex plane
Filomat, 2017 In the present paper, we obtain some new results by applying well-known Jack?s lemma. Moreover, the second-order differential subordinations associated with convex functions are also considered.
