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 ... -
On constructing total orders and solving vector optimization problems with total orders
(Springer, 2011)In this paper, we introduce a construction method of total ordering cone on R(n). It is shown that any total ordering cone on Rn is isomorphic to the cone R(lex)(n). Existence of a total ordering cone that contain given ... -
On deformations of G(2)-structures by Killing vector fields
(Walter De Gruyter GMBH, 2014)In this paper, vectorial type deformations of a 7-dimensional manifold with structure group G 2 are considered. The fundamental 3-form of such a manifold is deformed by a vector field, and the new cross product and the new ... -
On deformations of parallel G(2) structures and almost contact metric structures
(Walter De Gruyter GMBH, 2017)It is known that manifolds with G(2) structures have almost contact metric structures; see [3; 16]. In this manuscript, we deform a parallel G(2) structure by a parallel vector field and investigate the properties of the ... -
On differential inclusions with prescribed attainable sets
(Academic Press Inc Elsevier Science, 2003)In this article, the inverse problem of the differential inclusion theory is studied. For a given epsilon > 0 and a continuous set valued map t --> W(t), t is an element of [t(0), theta], where W(t) subset of R-n is compact ... -
On generalizations of extending modules
(Kyungpook National University, 2009)A module M is said to be SIP-extending if the intersection of every pair of direct summands is essential in a direct summand of M. SIP-extending modules are a proper generalization of both SIP-modules and extending modules. ... -
On generalized weak subdifferentials and some properties
(Taylor & Francis LTD, 2012)In this article, some characterizations for gw-subdifferentiability of functions from R-n to R-m are stated. Some criteria for gw-subdifferentiability of generalized lower locally Lipschitz functions and positively homogeneous ... -
On matrix rings with the SIP and the Ads
(Scientific Technical Research Council Turkey-Tubitak, 2018)In this paper, matrix rings with the summand intersection property (SIP) and the absolute direct summand (ads) property (briefly, SA) are studied. A ring R has the right SIP if the intersection of two direct summands of R ... -
On minimal representations by a family of sublinear functions
(Springer, 2015)This paper is a continuation of Grzybowski et al. (J Glob Optim 46:589-601, 2010) and is motivated by the study of exhausters i.e. families of closed convex sets. By Minkowski duality closed convex sets correspond to ... -
On modules and matrix rings with sip-extending
(Mathematical Soc Rep China, 2007)In this note we study modules with the property that the intersection of two direct summands is essential in a direct summand (SIP-extending). Amongst other results we show that the class of right SIP-extending modules is ... -
On One Application of Convex Optimization to Stability of Linear Systems
(Krasovskii Inst Mathematics & Mechanics Ural Branch Russian Acad Sciences, 2015)One of the most important problem of control theory is control of switched systems. This problem is related to the common quadratic Lyapunov function problem and one of the way to solve it is LMI (Linear Matrix Inequalities) ... -
On product and golden stuctures and harmonicity
(Scientific Technical Research Council Turkey-Tubitak, 2018)In this work, almost product and almost golden structures are studied. Conditions for those structures being integrable and parallel are investigated. Moreover, the harmonicity of a map between almost product or almost ... -
On Products of Uniquely Geodesic Spaces
(Mathematical Assoc Amer, 2015)After introducing the geodesic spaces, we prove that the product of two complete, uniquely geodesic spaces with respect to the product metric d(p) is again a uniquely geodesic space for 1 < p < infinity. -
On Self-Similar Subgroups in the Sense of IFS
(De Gruyter Open Ltd, 2018)In this paper, we first give several properties with respect to subgroups of self-similar groups in the sense of iterate function system (IFS). We then prove that some subgroups of p-adic numbers p are strong self-similar ... -
On Seven Dimensional 3-Sasakian Manifolds
(Ankara University, Fac Sci, 2016)3-Sasakian manifolds in dimension seven have cocalibrated and nearly parallel G(2)-structures. In this work, cocalibrated G(2)-structure is deformed by one of the characteristic vector fields of the 3-Sasakian structure ... -
On Some Finite Hyperbolic Spaces
(Charles Babbage Res Ctr, 2012)Let pi be a finite projective plane of order n. Consider the substructure pi(n+2) obtained from pi by removing n + 2 lines (including all points on them) no three are concurrent. In this paper, firstly, it is shown that ... -

(Springer, 2017)In this study, some optimality conditions for DCH-functions are given in terms of -faces using DC-duality approach. We introduce some geometric characterizations for the solution set of DCH-minimization problems by means ... -
