Existence of a Nonstationary Poiseuille Solution

Siberian Mathematical Journal, 2005
Let \(\omega\) be a bounded domain in \(\mathbb R^n\), \(Q_T = \omega\times(0,T)\). The following inverse problem is studied in \(Q_T\): \[ \begin{gathered} v_t(x,t) - \nu\Delta\,v(x,t) = q(t),\quad (x,t)\in Q_T, \\ v(x,t) = 0, \quad (x,t) \in \partial\omega\times(0,T),\quad v(x,0) = a(x),\quad x\in\omega, \\ \int_{\omega}v(x,t)\,dx = F(t)\;\;\text ...

Existence of solutions of pseudoconcave inequalities

Journal of Optimization Theory and Applications, 1980
Tucker's results for systems of linear inequalities are extended to nonlinear systems. Pseudoconcave or homogeneous functions are covered. The proof is performed through a simple, constrained extremum problem. Some applications are also suggested.

Existence of Regular Solutions

2014
In view of Theorems 4.2 and 4.10 and Remarks 4.7 and 4.9, we may seek the solutions of \((\mathrm{N}^+)\) and \((\mathrm{N}^-)\) in the form of \((V\varphi )^+\) and \((V\varphi )^-\) with \(\varphi \in \ 0\), that of \((\mathrm{D}^+)\) in the form of \((W\varphi )^+\) with \(\varphi \in \ 1\), and that of \((\mathrm{D}^-)\) as the sum of \((W\varphi )^
