An Evolution Equation Approach to the Klein-Gordon Operator on Curved Spacetime
Jan Dereziński, Daniel Siemssen
We develop a theory of the Klein-Gordon equation on curved spacetimes. Our main tool is the method of (non-autonomous) evolution equations on Hilbert spaces. This approach allows u…

Equations of hypergeometric type in the degenerate case
Jan Dereziński, Maciej Karczmarczyk
We consider the three most important equations of hypergeometric type, , and , in the so-called degenerate case. In this case one of the parameters, usu…

Quantization of Gaussians
Jan Dereziński, Maciej Karczmarczyk
Our paper is devoted to the oscillator semigroup, which can be defined as the set of operators whose kernels are centered Gaussian. Equivalently, they can be defined as the the Wey…
