FINITE TYPE LINK HOMOTOPY INVARIANTS [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 1999
In [2], Bar-Natan used unitrivalent diagrams to show that finite type invariants classify string links up to homotopy. In this paper, I will construct the correct spaces of chord diagrams and unitrivalent diagrams for links up to homotopy. I will use these spaces to show that, far from classifying links up to homotopy, the only rational finite type ...

1 Finite-State Automata: Characterization Finite-State Acceptors [PDF]

open access: yes, 2012
Definition (Non-deterministic finite-state acceptor (NFA)) A non-deterministic finite-state acceptor A is a 5-tuple (Q, Σ, q0, F, δ) where Q is a finite set of states Σ is the alphabet q0 ∈ Q is the start state F ⊆ Q is a set of final states δ: Q × Σ ...

OPERATOR METHOD IN THE INTERACTION PROBLEM OF THE SEMI-INFINITE VENETIAN BLINDTYPE GRATING AND FINITE STRIP GRATING

open access: yesRadio Physics and Radio Astronomy, 2015
The interaction problem of a semi-infinite venetian blind-type grating and finite strip grating is considered. The H-polarization case is studied. The problem solution is obtained by the operator method.

FINITE TYPE LINK CONCORDANCE INVARIANTS [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 2000
This paper is a follow-up to [10], in which the author showed that the only real-valued finite type invariants of link homotopy are the linking numbers of the components. In this paper, we extend the methods used to show that the only real-valued finite type invariants of link concordance are, again, the linking numbers of the components.

Analysis of a reaction-diffusion system of ƛ -w type [PDF]

open access: yes, 2003
The author studies two coupled reaction-diffusion equations of 'ƛ - w' type, on an open, bounded, convex domain Ω C R(^d) (d ≤ 3), with a boundary of class C(^2), and homogeneous Neumann boundary conditions.

Stiffness and Elastic Deformation of 4-DoF Parallel Manipulator with Three Asymmetrical Legs for Supporting Helicopter Rotor

open access: yesJournal of Robotics, 2020
The stiffness and elastic deformation of a 4-DoF parallel manipulator with three asymmetrical legs are studied systematically for supporting helicopter rotor. First, a 4-DoF 2SPS + RRPR type parallel manipulator with two linear SPS type legs and one RRPR

Rellich-type Discrete Compactness for Some Discontinuous Galerkin FEM [PDF]

open access: yes
We deduce discrete compactness of Rellich type for some discontinuous Galerkin finite element methods (DGFEM) including hybrid ones, under fairly general settings on the triangulations and the finite element spaces.

A Note on Marcinkiewicz Integrals along Submanifolds of Finite Type

open access: yesJournal of Function Spaces, 2018
We study the parametric Marcinkiewicz integrals along submanifolds of finite type with rough kernels. The kernels of our operators are allowed to be very rough both on the unit sphere and in the radial direction. Under the rather weakened size conditions
