Some Zaremba-Hopf-Oleinik Boundary Comparison Principles at Characteristic Points
Bruno Pini Mathematical Analysis Seminar, 2015 We investigate the so-called Hopf lemma for certain degenerate-elliptic equations at characteristic boundary points of bounded open sets. For such equations, the validity of the Hopf lemma is related to the fact that the boundary of the open set reflects

Solving the Axisymmetric Inverse Heat Conduction Problem by a Wavelet Dual Least Squares Method
Boundary Value Problems, 2009 We consider an axisymmetric inverse heat conduction problem of determining the surface temperature from a fixed location inside a cylinder. This problem is ill-posed; the solution (if it exists) does not depend continuously on the data.

Existence and Nonexistence Results for a Class of Quasilinear Elliptic Systems
Boundary Value Problems, 2007 Using variational methods, we prove the existence and nonexistence of positive solutions for a class of (p,q)-Laplacian systems with a parameter.

Monotone iterative technique for semilinear elliptic systems
Boundary Value Problems, 2005 We develop monotone iterative technique for a system of semilinear elliptic boundary value problems when the forcing function is the sum of Caratheodory functions which are nondecreasing and nonincreasing, respectively.

On coupled systems of Hammerstein integral equations
Boundary Value Problems, 2019 In this paper we deal with generalized coupled systems of integral equations of Hammerstein type with nonlinearities depending on several derivatives of both variables and we underline that both equations and both variables can have a different ...

Boundary Value Problems, 2019 In this paper, we consider a Sturm–Liouville problem with finite discontinuous points inside an interval and with abstract linear functionals in the boundary and transmission conditions.

Differential forms in Carnot groups: a variational approach
Bruno Pini Mathematical Analysis Seminar, 2011 Carnot groups (connected simply connected nilpotent stratified Lie groups) can be endowed with a complex of ``intrinsic'' differential forms. In this paper we want to provide an evidence of the intrinsic character of Rumin's complex, in the spirit of the

Boundary Value Problems, 2009 An initial-boundary value problem for 1D flow of a compressible viscous heat-conducting micropolar fluid is considered; the fluid is thermodynamically perfect and polytropic.

Blowup for degenerate and singular parabolic system with nonlocal source
Boundary Value Problems, 2006 We deal with the blowup properties of the solution to the degenerate and singular parabolic system with nonlocal source and homogeneous Dirichlet boundary conditions.
