Rationale and design of the TRIC‐I‐HF‐DZHK24 (TRICuspid Intervention in Heart Failure) trial

European Journal of Heart Failure, EarlyView.
Study overview of the TRIC‐I‐HF‐DZHK24 trial. HF, heart failure; HFH, heart failure hospitalization; QoL, quality of life; RHC, right heart catheterization; TR, tricuspid regurgitation; TTVI, transcatheter tricuspid valve intervention. Abstract Aims Tricuspid regurgitation (TR) is a detrimental disease frequently diagnosed in patients with right‐sided ...

Verification of Positive Definiteness

BIT Numerical Mathematics, 2006
We present a computational, simple and fast sufficient criterion to verify positive definiteness of a symmetric or Hermitian matrix. The criterion uses only standard floating-point operations in rounding to nearest, it is rigorous, it takes into account all possible computational and rounding errors, and is also valid in the presence of underflow.

On Different Definitions of Positive Definiteness

Mathematische Nachrichten, 1991
Let the function \(T^*\) be defined by \(T^*(a)=T(a^{-1})^*\) for a function \(T\) of a group \(G\) into a Hilbert space. The authors show that the commutativity of \(G\) is equivalent to each of the conditions below: (1) \(T^*\) is positive definite for every representation \(T\) of \(G\) in Hilbert space.
