Seiberg-Witten type monopole equations on 8-manifolds with Spin(7) holonomy as minimizers of a quadratic action
(Springer, 2003)We obtain an elliptic system of monopole equations on 8-manifolds with Spin(7) holonomy by minimizing an action involving negative spinors coupled to an abelian gauge field. -
Monopole equations on 8-manifolds with spin(7) holonomy
(Springer Verlag, 1999)We construct a consistent set of monopole equations on eight-manifolds with Spin(7) holonomy. These equations are elliptic and admit non-trivial solutions including all the 4-dimensional Seiberg-Witten solutions as a special case. -
The common vector approach and its comparison with other subspace methods in case of sufficient data
(Academic Press LTD- Elsevier Science LTD, 2007)This paper presents an application of the common vector approach (CVA), an approach mainly used for speech recognition problems when the number of data items exceeds the dimension of the feature vectors. The calculation ... -
Canonical bases for real representations of Clifford algebras
(Elsevier Science Inc, 2006)The well-known classification of the Clifford algebras Cl(r, s) leads to canonical forms of complex and real representations which are essentially unique by virtue of the Wedderburn theorem. For s >= 1 representations of ... -
The geometry of self-dual two-forms
(Amer Inst Physics, 1997)We show that self-dual two-forms in 2n-dimensional spaces determine a n(2)-n+1-dimensional manifold S-2n and the dimension of the maximal linear subspaces of S-2n is equal To the (Radon-Hurwitz) number of linearly independent ... -
A novel approach to isolated word recognition
(IEEE-Inst Electrical Electronics Engineers Inc, 1999)A voice signal contains the psychological and physiological properties of the speaker as well as dialect differences, acoustical environment effects, and phase differences. For these reasons, the same word uttered by ... -
Comparisons of rotordynamic coefficients in stepped labyrinth seals by using Colebrook-White friction factor model
(Springer, 2007)The objective of this work is to observe the effects of friction factors for the stepped labyrinth seals. The gas flow through the seals creates net pressure and shear forces acting on the rotor. It is necessary to predict ... -
Effects of shear stress forces to rotordynamic coefficients in staggered labyrinth seals
(Professional Engineering Publishing LTD, 2006)In this article, shear stresses in calculating the rotordynamic coefficients of staggered labyrinth seals are presented. Differences in the values of these coefficients are observed and quantified. The results of the present ... -
Constancy of some maps into f-manifolds
(Belgian Mathematical Soc Triomphe, 2006)Constancy of some maps into certain f-manifolds is discussed. -
On solution of boundary value problem for differential inclusion
(Pergamon-Elsevier Science LTD, 2000)In the article an inverse problem for differential inclusion is considered. For a given compact set M-* subset of R-n it is required to define the maximal set M-0 subset of R-n so that the reachable set of differential ... -
On the directional differentiability properties of the marginal function
(Pergamon-Elsevier Science LTD, 2002)In this paper, by using the directional lower and upper derivative of a set-valued map, the directional lower and upper derivatives of marginal function are investigated. Sufficient condition, ensuring the existence of the ... -
Existence of a dense orbit and topological transitivity: When are they equivalent?
(Akademiai Kiado, 2003)Topological transitivity and existence of a dense orbit are two notions which play an important role in every definition of chaos [2], [4]. Unfortunately, in the literature there are often misunderstandings (or even false ... -
Solitary Wave Solutions of the MRLW Equation Using Radial Basis Functions
(Wiley-Blackwell, 2012)In this study, traveling wave solutions of the modified regularized long wave (MRLW) equation are simulated by using the meshless method based on collocation with well-known radial basis functions. The method is tested for ... -
Convex extensions of the convex set valued maps
(Academic Press Inc Elsevier Science, 2006)In this article the existence of the convex extension of convex set valued map is considered. Conditions are obtained, based on the notion of the derivative of set valued maps, which guarantee the existence of convex ... -
On the continuity properties of the attainable sets of control systems with integral constraints on control
(Pergamon-Elsevier Science LTD, 2004)In the paper the attainable sets of the control systems with integral constraints on control are studied. It is assumed that the system is nonlinear with respect to the phase state vector and linear with respect to the ... -
On the continuity property of L-P balls and an application
(Academic Press Inc Elsevier Science, 2007)In this paper continuity properties of the set-valued map p -> B-p(mu(0)), p is an element of (1, +infinity), are considered where B-p (mu(0)) is the closed ball of the space L-p ([t(0), theta]; R-m) centered at the origin ... -
The space of irreducible SU(2) representations of the twist knots
(World Scientific Publ Co Pte LTD, 2004)In this work we classify the space of irreducible SU(2) representations of the groups of the twist knots by means of a geometric method which is generalizable to all the 2-bridge knots. -
Seiberg-Witten-like equations on 7-manifolds with G(2)-structure
(Norbert Euler, 2005)The Seiberg-Witten equations are of great importance in the study of topology of smooth four-dimensional manifolds. In this work, we propose similar equations for 7-dimensional compact manifolds with G(2)-structure. -
The meshless kernel-based method of lines for the numerical solution of the nonlinear Schrodinger equation
(Elsevier Sci LTD, 2012)In this paper, the nonlinear Schrodinger equation is solved numerically by using the meshless kernel-based method of lines. Multiquadric, Gaussian and Wend land's compactly supported radial basis functions are used as the ...
