We use these to show that a segmentation approach to the EIT inverse problem has a unique solution in a suitable space using a fixed point

Furthermore, the upper semicontinuity of the global attractor for a singularly perturbed phase-field model is proved in [12] (see also [11] for a logarithmic nonlinearity) for two

We present sufficient conditions for the existence of solutions to Neu- mann and periodic boundary-value problems for some class of quasilinear ordinary differential equations.. We

If you want to study different themes and learn how to talk about them more naturally in English, please apply to join one of my classes.

Then it follows immediately from a suitable version of “Hensel’s Lemma” [cf., e.g., the argument of [4], Lemma 2.1] that S may be obtained, as the notation suggests, as the m A

Jin [21] proved by nonstandard methods the following beautiful property: If A and B are sets of natural numbers with positive upper Banach density, then the corresponding sumset A +
