A First Course on Pseudo-Differential Operators

10 oct. 2017 The Fourier transformation can be extended to a unitary operator of L2(Rn) i.e. there exists a unique bounded linear operator F : L2(Rn) ...

Pseudo-Differential Operators Involving Fractional Fourier Cosine

Fractional Fourier cosine (fractional Fourier sine) transform of tempered distributions is studied. Pseudo-differential operators involving these

FOURIER TRANSFORM Very broadly speaking the Fourier

This leads to the theory of fractional differential operators (which are in turn a special case of pseudodifferential operators) as well as the more general
