چکیده

M. Khovanov and L. Rozansky gave a categorification of the HOMFLY-PT polynomial. This study is a generalization of the Khovanov-Rozansky homology. We define a homology associated to the quantum (sln,∧Vn) link invariant, where ∧Vn is the set of the fundamental representations of the quantum group of sln. In the case of a [1, k]-colored link diagram, we prove that its homology is a link invariant. In the case of an [i, j]-colored link diagram, we define a normalized Poincaré polynomial of its homology and prove the polynomial is a link invariant.

MATRIX FACTORIZATIONS AND INTERTWINERS OF THE FUNDAMENTAL REPRESENTATIONS OF QUANTUM GROUP Uq(sln)

We want to construct a homological link invariant whose Euler characteristic is MOY polynomial as Khovanov and Rozansky constructed a categorification of HOMFLY polynomial. The present paper gives the first step to construct a categorification of MOY polynomial. For the essential colored planar diagrams with additional data which is a sequence naturally induced by coloring, we define matrix fac...

A COLORED sl(N)-HOMOLOGY FOR LINKS IN S 3

Fix an integer N ≥ 2. To each diagram of a link colored by 1, . . . , N , we associate a chain complex of graded matrix factorizations. We prove that the homopoty type of this chain complex is invariant under Reidemeister moves. When every component of the link is colored by 1, this chain complex is isomorphic to the chain complex defined by Khovanov and Rozansky in [17]. We call the homology o...

Matrix Factorizations and Colored Moy Graphs

We assign matrix factorizations to colored MOY graphs, which gives a natural generalization of the graph homology defined by Khovanov and Rozansky in [8]. We also discuss some basic properties of this generalization. This work is a first step toward categorification of the colored MOY invariant, which is equivalent to quantum sl(N)-invariant for links whose components are colored by exterior pr...

MATRIX FACTORIZATIONS AND DOUBLE LINE IN sln QUANTUM LINK INVARIANT

L. Kauffman introduced a graphical link invariant which is the normalized Jones polynomial [4][5]. It is well-known that the polynomial is derived from the fundamental representation of the quantum group Uq(sl2). Further, G. Kuperberg constructed a graphical link invariant associated with the fundamental representation of the quantum group Uq(sl3) [10]. H. Murakami, T. Ohtsuki and S. Yamada int...

QFT Control of a Two-Link Rigid-Flexible Manipulator

This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...
