Discrete Symbol Calculus
sublinear complexity inversion of elliptic operators square root of elliptic operators
2015/7/14
This paper deals with efficient numerical representation and manipulation of differential and integral operators as symbols in phase-space, i.e., functions of space x and frequency ξ. The symbol smoot...
We consider the problem of constructing a wave extrapolation operator in a variable and possibly anisotropic medium. Our construction involves Fourier transforms in space combined with the help of a l...
Projectively Equivariant Quantization and Symbol calculus in dimension 1|2
Equivariant Quantization Symbol calculus dimension 1|2 Differential Geometry
2011/7/26
Abstract: The spaces of higher-order differential operators (in Dimension 1|2), which are modules over the stringy Lie superalgebra K(2), are isomorphic to the corresponding spaces of symbols as ortho...
$L^p$ and Sobolev boundedness of pseudodifferential operators with non-regular symbol: a regularisation approach
Sobolev boundedness pseudodifferential operators non-regular symbol
2010/11/11
In this paper we investigate $L^p$ and Sobolev boundedness of a certain class of pseudodifferential operators with non-regular symbols. We employ regularisation methods, namely convolution with a net ...
Coupling Property and Gradient Estimates of Lévy Processes via the Symbol
Coupling Property Gradient Estimates Lévy Processes via the Symbol
2010/11/11
We derive explicitly the coupling property for the transition semigroup of a L\'evy process and gradient estimates for the associated semigroup of transition operators. This is based on the asymptoti...
Grounded Symbols in the Brain Computational Foundations for Perceptual Symbol System
Grounded Symbols Brain Computational Foundations Perceptual Symbol System
2010/11/15
We describe a mathematical models of grounded symbols in the brain. It also serves as a computational foundations for Perceptual Symbol System (PSS). This development requires new mathematical methods...
Solving the Symbol Grounding Problem: a Critical Review of Fifteen Years of Research
artificial agent commitment symbol grounding problem
2011/9/8
This article reviews eight proposed strategies for solving the Symbol Grounding Problem (SGP), which was given its classic formulation in Harnad (1990). After a concise introduction, we provide an ana...
A Praxical Solution of the Symbol Grounding Problem
artificial evolution local selection Symbol Grounding Problem
2011/9/8
This article is the second step in our research into the Symbol Grounding Problem (SGP). In a previous work, we defined the main condition that must be satisfied by any strategy in order to provide a ...
Recurrence relation for the 6j-symbol of su_q(2) from an eigenvalue problem
Racah-Wigner coefficients 6j-symbol quantum group eigenvalue problem
2010/12/3
A new, linear, three-term recurrence relation for the 6j-symbol of the quantum group suq(2) is derived. It is cast in the form of a symmetric eigenvalue problem, generalizing a result of Schulten and ...

Channel-coded Collision Resolution Symbol Misalignment
2010/12/9
In random-access networks, such as the IEEE 802.11 network, different users may transmit their packets simultaneously,resulting in packet collisions.
