Spectral Doubling of Normal Operators and Connections with Antiunitary Operators

Integral Equations and Operator Theory, 2011
Let \(H\) be a complex separable Hilbert space and let \(B(H)\) denote the algebra of all bounded linear operators on \(H\). An antilinear map \(J:H\to H\) is called antiunitary if it is onto and \((Jx,Jy)=(y,x)\) for every \(x,y\in H\). If, in addition, \(J^2=I\), then \(J\) is called a conjugation.

Matrix Operations Induced by Network Connections

SIAM Journal on Control, 1975
The interconnection of two electrical networks is used to define an operation, called the router sum, on the corresponding impedance matrices. For the special case of the series connection, the router sum is the ordinary matrix sum ; for the parallel connection, the parallel sum is obtained [3].

Operational Activity and Connections

2019
This chapter sheds light on the operational activities of “terrorist asylum-seekers” in Europe, as well as the nature of connections to foreign terrorist organizations (FTOs) and involvement in crime. Although connections are found to more than a dozen FTOs, the majority are linked to ISIS.

An Operation Connected to a Young‐Type Inequality

Mathematische Nachrichten, 1992
AbstractGiven two φ‐functions F and G we consider the largest φ‐function H = F ⊕ G such that the Young‐type inequality H(xy) ⩽ F(x) + G(y) holds for all x, y > 0. We prove an equivalence theorem for F ⊕ G with the best constants and, for the special case when F and G are log‐convex and satisfy a certain growth condition, a representation formula for

Operators with connected spectrum + compact operators = strongly irreducible operators

Science in China Series A: Mathematics, 1999
Let \(L(H)\) be the algebra of all bounded linear operators acting on a complex, separable, infinite-dimensional Hilbert space \(H\). An operator \(T\in L(H)\) is said to be strongly irreducible if it does not commute with any nontrivial idempotents. It is proved that each operator \(T\in L(H)\) with connected spectrum can be represented as the sum of ...

Connected operators based on region-trees

2008 15th IEEE International Conference on Image Processing, 2008
Connected operators are operators that act by merging of elementary regions called flat zones. They cannot create new contours nor modify their position. Therefore, they have very good contour preservation properties. This paper discusses connected operators based on region trees.

Operator-valued connections, Lie connections, and Gauge field theory

International Journal of Theoretical Physics, 1984
This paper proposes a generalization of the gauge theories that are based on connections with values in a Lie algebra. This objective is attained as follows. Let \(M_ n\) be the base space of the independent variables, and \(R^ N\) the range space of the state variables.

Connected Operators for Signal and Image Processing

2006
Data and signal modeling for images and video sequences is experiencing important developments. Part of this evolution is due to the need to support a large number of new multimedia services. Traditionally, digital images were represented as rectangular arrays of pixels and digital video was seen as a continuous flow of digital images.
