Hörmander operators are a class of linear second order partial differential operators with nonnegative characteristic form and smooth coefficients, which are usually degenerate elliptic-parabolic, but nevertheless hypoelliptic, that is highly regularizing.

Operators from a Hilbert space \(H\) to itself have many applications, ranging from linear integral equations to quantum physics. Many of these applications use known properties of operators such as their spectral decomposition. Because of these applications, it is desirable to analyze when the corresponding mathematical existence theorems can be ...

Operator-Stable Quantum Probability Operators
Journal of Mathematical Sciences, 2001Let \(V(z)\), \(z\in {\mathbb R}^{2s}\), denote a projective unitary representation of \({\mathbb R}^{2s}\) satisfying the Weyl-Segal commutation relation. Given a probability operator (i.e. a positive operator with unit trace) \(T\) in the space \({\mathcal L}_1\) of nuclear operators on a separable infinite-dimensional Hilbert space \({\mathcal H}\),

Operation RUVANDIZ-SCHLUCHT (ROWANDUZ GORGE) is said to have been a detailed scheme originally submitted to Hans-Otto Wagner of Abwehr II in 1941 by Paul Leverkuehn of KONO in Istanbul for a 2–3-man parachute team to carry out the demolition of bridges on the 185 km-long, strategic asphalt road, known even today as the Hamilton Road, constructed by the

Pre-operative, Operative and Postoperative Guidelines
1974There is a high tendency towards post-traumatic swelling of the hand and foot, which must be considered in the timing of the operation. Operation must either be carried out immediately, or after swelling has decreased, which means a delay of some days. Where operation is postponed, the skin of the operation site should on the eve of the intervention be

ACM SIGMOD Record, 2000
This paper discusses issues related to the integration of spatial operators into the new generation of SQL-like query languages. Starting from spatial data models, current spatial extensions of query languages are briefly reviewed and research directions are highlighted.
