Maximum and antimaximum principles for the $p$-Laplacian with weighted Steklov boundary conditions
Electronic Journal of Differential Equations, 2020 We study the maximum and antimaximum principles for the p-Laplacian operator under Steklov boundary conditions with an indefinite weight $$\displaylines{ -\Delta_p u + |u|^{p-2}u = 0 \quad \text{in }\Omega, \cr |\nabla u|^{p-2}\frac{\partial u ...

On maximum principles for monotone matrices
Linear Algebra and its Applications, 1986 The (n,n)-matrix A satisfies the maximum principle if \(Ay=f\) and \(f\geq 0\) implies \(y\geq 0\), and moreover \(\max \{y_ i|\) \(i\in N\}=\max \{y_ i| i\in N^+(f)\}\) with \(N=\{1,...,n\}\) and \(N^+(f)=\{j\in N| f_ j>0\}\). Define \(A^{(+)}=a_{ij}\) for \(i\neq j\) and \(a_{ij}>0\) and 0 elsewhere. The following holds.

Advanced Engineering Materials, EarlyView.The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of
