摘要：TClassic hypercomplex analysis is intimately linked with elliptic operators, such as the Laplacian or the Dirac operator, and positive quadratic forms. But there are many applications like the inver[1]sion of the crystallographic X-ray transform, the study of solutions of the ultrahyperbolic Dirac operator, or machine/deep learning problems which are closely connected with indefinite quadratic forms. Among other things this is due to the possibility of the underlying Clifford algebra to have a signature (p, q) and, therefore, to be linked to Pontryagin modules instead of Hilbert modules. Although in the majority of papers Hilbert modules are being used in this context they are not the right choice as function spaces since they do not reflect the induced geometry. In this talk we are going to show that Clifford-Krein modules are naturally appearing in this context. We take a partic[1]ular look into the case of Clifford-Krein modules with reproducing kernels and discuss applications in interpolation and sampling problems.
