3) negative definite quadratic form 负定二次型 1. The conditions of equivalence of negative definite quadratic form and negative semidefinitequadratic form are given according to their definitions and some properties of negative definitematrices are given too in the paper. 本文根据负定二次型与半...
In this paragraph shall we introduce the negative definite functions. After giving some equivalent formulations of the notion of negative definiteness, elementary properties and simple examples of negative definite functions are discussed. Many of the considerations are of an algebraic nature and do not...
The integral representation theorems for positive and negative definite functions obtained so far were all proved under the assumption that the semigroup contained a neutral element, i.e. a "zero" with respect to the additively written semigroup operation. We also saw that some boundedness ...
The question of extendingLp-sub-Markovian semigroups to the spacesLq,q>p, and the interpolation ofLp-sub-Markovian semigroups with Feller semigroups is investigated. The structure of generators ofLp-sub-Markovian semigroups is studied. Subordination in the sense of Bochner is used to discuss...

Determining rigid body motion from accelerometer data through the square-root of a negative semi-definite tensor, with applications in mild traumatic brain injuryMild Traumatic Brain Injuries (mTBI) are caused by violent head motions or impacts. Most mTBI prevention strategies explicitly or implicitly ...

Moreover, using the similar idea, we can show that the minimal H-eigenvalue of a symmetric space tensor must be the optimal value of a semi-definite program. Computational results and discussions are provided to illustrate the significance of the results and the effectiveness of the proposed ...
