Characterization of the Lovelock-Palatini Lagrangians with an arbitrary connection
Characterization Lovelock-Palatini Lagrangians arbitrary connection
2011/3/2
We define the concept of Levi Civita truncation for a Lagrangian in the Palatini formulation with an arbitrary connection, and show that its consistency uniquely identifies the Lovelock Lagrangians.
Ritt-Wu's Characteristic Set Method For Ordinary Di®erence Polynomial Systems With Arbitrary Ordering
dierence polynomial ascending chain characteristic set Ritt-Wu's zero decomposition theorem
2013/9/9
In this paper, a new Ritt-Wu's characteristic set method for ordinary di®erence systems is proposed, which is valid for any admissible ordering. New deˉnition for irreducible chains and new zero ...
Let m be a finite measure, E a Banach space, and 1\leq p <\infty, \, 1ty be such that \frac{1}{p}+\frac{1}{q}=1. It is known that Lp(m,E)*\simeq Lq(m,E*) if, and only if, E* has the Radon-N...
