Maximum and anti-maximum principles for the general operator of second order with variable coefficients

Applied Mathematics and Computation, 2003
The authors study positivity or negativity properties of the general linear second-order operator \[ L(p,q)u(t)=u''(t)+p(t)u'(t)+q(t)u(t), \quad t\in J=[0,R], \] where \(p, q\in L_1(J)\) are given and Neumann boundary conditions are considered. As a consequence of the results obtained for the Neumann problem, the authors deduce analogous results for ...

PROBABILISTIC STABILITY, AGM REVISION OPERATORS AND MAXIMUM ENTROPY

The Review of Symbolic Logic, 2020
AbstractSeveral authors have investigated the question of whether canonical logic-based accounts of belief revision, and especially the theory of AGM revision operators, are compatible with the dynamics of Bayesian conditioning. Here we show that Leitgeb’s stability rule for acceptance, which has been offered as a possible solution to the Lottery ...

The Atmosphere as a Heat Engine Operating at Maximum Power

Journal of Climate
Abstract Earth’s atmosphere has long been conceived of as a heat engine driven by the insolation gradients imposed by spherical geometry. In the mid-1950s, Lorenz suggested that the general circulation operates at “maximum intensity,” or maximum kinetic energy.

Waldenfels Operators and Maximum Principles

2014
In this chapter, following Bony–Courrege–Priouret [BCP], we prove the weak and strong maximum principles and Hopf’s boundary point lemma for second-order elliptic Waldenfels operators which play an essential role throughout the book.

Elliptic Waldenfels Operators and Maximum Principles

2020
Part IV (Chapters 10 and 11) is devoted to the general study of the maximum principles for second-order, elliptic Waldenfels operators in terms of pseudo-differential operators.

Boundary Operators and Boundary Maximum Principles

2020
Let D be a bounded domain of Euclidean space RN, with smooth boundary ∂D; its closure \(\overline {D} = D \cup {\partial D}\) is an N-dimensional, compact smooth manifold with boundary (see Figure 11.1 below). In this chapter, following Bony–Courrege–Priouret ( [15, Chapter II]) we characterize Ventcel’–Levy boundary operators T (Theorem 11.3) and ...
