ON FOURIER INTEGRAL OPERATORS

Mathematics of the USSR-Sbornik, 1981
On the basis of the stationary phase method for oscillatory integrals with complex phase function, the authors prove the coincidence of Fourier integral operators and Maslov's canonical operator. Bibliography: 17 titles.

Integrated operations

IEEE Journal on Selected Areas in Communications, 1988
The value of and reasons for integrating operations systems (OSs) with each other and with network elements are discussed. The reasons for integrating current OSs are: to provide added value resulting from the synergy of capabilities implemented in each individual OS; to increase the flexibility of the overall system and the diversity of methods and ...

On Carleman Integral Operators

Canadian Mathematical Bulletin, 1970
L2(a, b)1with the property2were originally defined by T. Carleman [4]. Here he imposed on the kernel the conditions of measurability and hermiticity,3for all x with the exception of a countable set with a finite number of limit points and4where Jδ denotes the interval [a, b] with the exception of subintervals |x - ξv| < δ; here ξv represents a ...

Regularity of Integral Operators

Integral Equations and Operator Theory, 2004
The article aims on providing a proper analogue to the Hörmander condition for an integral operator to be bounded \(L^p\rightarrow I_\alpha(L^p)\), where the Sobolev space \(I_\alpha(L^p)\) is the image of \(L^p\) under the convolution with the Riesz potential \(I_\alpha: f\rightarrow (| \xi| ^{-\alpha} \widehat{f})^\vee\).

Operational amplifier integrator

An integrator circuit comprises an operational amplifier which has a transistor stage (1) with an input terminal (4) and an output terminal (3), a feedback capacitor (2) connected between the input terminal (4) and the output terminal (3), and a resistor (5) connected to the input terminal (4), and also has an additional circuit branch (20) comprising ...
