Symbol Classes and Function SpacesIn this chapter we initiate the study of continuity properties for Born–Jordan operators. We will discuss the global symbol classes introduced by Shubin; they are “global” in the sense that they satisfy growth estimates with an equal weighting on the position and momentum variables.

Book 2016tures of quantum mechanics are equivalent only if the Born–Jordan scheme is used. Thus, Born–Jordan quantization provides the only physically consistent quantization scheme, as opposed to the Weyl quantization commonly used by physicists. In this book we develop Born–Jordan quantization from an oper

https://doi.org/10.1007/b138344d discuss some unexpected properties of these operators; for instance we will show that Born–Jordan quantization is not one-to-one: the zero operator is the quantization of infinitely many classical phase space functions. Another approach, based on Shubin’s theory of pseudo-differential operators, will be developed in the forthcoming chapters.

Book 2016aches, in particular the Feynman-integral point of view. One important and intriguing feature of Born-Jordan quantization is that it is not one-to-one: there are infinitely many classical observables whose quantization is zero..
