On the Set of Trajectories of the Control Systems with Limited Control Resources
(Springer-Verlag Berlin, 2015)
The set of trajectories of the control system with limited control resources is studied. It is assumed that the behavior of the system is described by a Volterra type integral equation which is nonlinear with respect to ...
Large margin classifiers based on affine hulls
(Elsevier Science BV, 2010)
This paper introduces a geometrically inspired large margin classifier that can be a better alternative to the support vector machines (SVMs) for the classification problems with limited number of training samples. In ...
Generalized weak subdifferentials
(Taylor & Francis LTD, 2011)
In this article, generalized weak subgradient (gw-subgradient) and generalized weak subdifferential (gw-subdifferential) are defined for nonconvex functions with values in an ordered vector space. Convexity and closedness ...
Goldie-Supplemented Modules
(Cambridge University Press, 2010)
Motivated by a relation on submodules of a module used by both A. W. Goldie and P. F. Smith, we say submodules X, Y of M are beta* equivalent, X beta* Y, if and only if X + Y/X is small in M/X and X + Y/Y is small in M/Y. ...
The Euler characteristic and signature of four-dimensional closed manifolds and the normalized Ricci flow equation
(Springer, 2016)
Let M be a closed manifold of dimension four, and let [0, T) be the maximal time interval for the normalized Ricci flow equation. We prove that, if the normalized Ricci flow equation has a solution on the non-negative real ...
On Strongly Precontinuous Functions
(Springer, 2008)
In this paper, we give some characterizations of strongly precontinuous functions. Also we investigate some special properties of these function.
On Ads-Modules With the Sip
(Iranian Mathematical Soc, 2015)
The class of ads modules with the SIP (briefly, SA-modules) is studied. Various conditions for a module to be SA-module are given. It is proved that for a quasi-continuous module M, M is a UC-module if and only if M is an ...
Graphical Understanding in Mathematics Education: Derivative Functions and Students' Difficulties
(Elsevier Science BV, 2012)
Effective teaching is one of the most important factors to improve students' achievement. Therefore, many researchers in mathematics education are looking for several ways to improve the quality of learning. The purpose ...
Amply (weakly) Goldie-Rad-supplemented modules
(Inst Applied Mathematics & Mechanics Natl Acad Sciences Ukraine, 2016)
Let R be a ring and M be a right R-module. We say a submodule S of M is a (weak) Goldie-Rad-supplement of a submodule N in M, if M = N + S, (N boolean AND S <= Rad(M)) N boolean AND S <= Rad(S) and N beta**S, andM is called ...
Weak Conjugate Duality for Nonconvex Vector Optimization
(Yokohama Publishers, 2017)
In this work, weak conjugate map, weak biconjugate map and weak subdifferential of a set-valued map are defined by using notions of supremum/infimum of a set and vectorial norm, and relationships among these notions are ...
