Existence and localization of solutions for fourth-order boundary-value problems
Electronic Journal of Differential Equations, 2007 In this paper, we study the existence of solutions for the differential equation $$ u^{(4)}(t)=fig(t,u(t),u''(t)ig), $$ where $f$ satisfies one-sided Lipschitz conditions with respect to $u$ and $u''$, with periodic conditions or boundary conditions from

Thermodynamic resource theories, non-commutativity and maximum entropy principles
New Journal of Physics, 2017 We discuss some features of thermodynamics in the presence of multiple conserved quantities. We prove a generalisation of Landauer principle illustrating tradeoffs between the erasure costs paid in different ‘currencies’.

Maximum principles for viscosity solutions of weakly elliptic equations
Bruno Pini Mathematical Analysis Seminar, 2019 Maximum principles play an important role in the theory of elliptic equations. In the last decades there have been many contributions related to the development of fully nonlinear equations and viscosity solutions.

Optimal Conditions for Maximum and Antimaximum Principles of the Periodic Solution Problem
Boundary Value Problems, 2010 Given a periodic, integrable potential q(t), we will study conditions on q(t) so that the operator Lqx=x″+qx admits the maximum principle or the antimaximum principle with respect to the periodic boundary condition.

Entropy Production and Viscosity of A Dilute Gas
, 2012 It is known that the viscosity of a dilute gas can be derived by using kinetic theory. We present here a new derivation by using two entropy production principles: the steepest entropy ascent (SEA) principle and the maximum entropy production (MEP ...

A remark on Einstein warped products
, 2010 We prove triviality results for Einstein warped products with non-compact bases. These extend previous work by D.-S. Kim and Y.-H. Kim. The proof, from the viewpoint of "quasi-Einstein manifolds" introduced by J. Case, Y.-S. Shu and G.

On maximum-entropy and related principles in statistical equilibrium
International Journal of Mathematics and Mathematical Sciences, 1990 The paper aims to study the importance and equivalence of the principles of maximum-entropy, and sufficient and stable inferences in the statistical characterization of the thermal equilibrium of a closed system.

The classical overdetermined Serrin problem
, 2017 In this survey we consider the classical overdetermined problem which was studied by Serrin in 1971. The original proof relies on Alexandrov's moving plane method, maximum principles, and a refinement of Hopf's boundary point Lemma.
