A Goursat decomposition for polyharmonic functions in Euclidean space [PDF]

open access: yes, 2012
The Goursat representation formula in the complex plane, expressing a real–valued biharmonic function in terms of two holomorphic functions and their anti–holomorphic complex conjugates, is generalized to Euclidean space, expressing a real–valued ...

(R, S)-(Skew) Symmetric Solutions to Matrix Equation AXB = C over Quaternions

open access: yesMathematics
(R,S)-(skew) symmetric matrices have numerous applications in civil engineering, information theory, numerical analysis, etc. In this paper, we deal with the (R,S)-(skew) symmetric solutions to the quaternion matrix equation AXB=C.

Real-Time Representations of the Output Gap [PDF]

open access: yesReview of Economics and Statistics, 2008
Methods are described for the appropriate use of data obtained and analysed in real time to represent the output gap. The methods employ cointegrating VAR techniques to model real-time measures and realizations of output series jointly. The model is used to mitigate the impact of data revisions; to generate appropriate forecasts that can deliver ...

Solution to Several Split Quaternion Matrix Equations

open access: yesMathematics
Split quaternions have various applications in mathematics, computer graphics, robotics, physics, and so on. In this paper, two useful, real representations of a split quaternion matrix are proposed. Based on this, we derive their fundamental properties.

A System of Tensor Equations over the Dual Split Quaternion Algebra with an Application

open access: yesMathematics
In this paper, we propose a definition of block tensors and the real representation of tensors. Equipped with the simplification method, i.e., the real representation along with the M-P inverse, we demonstrate the conditions that are necessary and ...

On the relation between the connection and the loop representation of quantum gravity [PDF]

open access: yes, 1996
Using Penrose binor calculus for $SU(2)$ ($SL(2,C)$) tensor expressions, a graphical method for the connection representation of Euclidean Quantum Gravity (real connection) is constructed.

Semidefinite representation for convex hulls of real algebraic curves

open access: yes, 2017
We show that the closed convex hull of any one-dimensional semi-algebraic subset of R^n has a semidefinite representation, meaning that it can be written as a linear projection of the solution set of some linear matrix inequality.

Representation Theory of Quantized Enveloping Algebras with Interpolating Real Structure

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
Let g be a compact simple Lie algebra. We modify the quantized enveloping ∗-algebra associated to g by a real-valued character on the positive part of the root lattice.

The touch of the real. Il New Historicism e il potere del reale psichiatrico in Foucault [PDF]

open access: yesLaboratorio dell'ISPF, 2014
[The touch of the real. The New Historicism and the power of the psychiatric real in Foucault] What is the meaning of “touch of the real”? This paper connects the new historicist Greenblatt’s phrase to Foucault’s use of the term real during his lecture ...

Real‐World Pediatric Blinatumomab Administration: Access to Outpatient Care Delivery and Impact of a Hospital‐Dispensed Model

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.
