On elliptic problems with Choquard term and singular nonlinearity

Debajyoti Choudhuri, Dušan D. Repovš, Kamel Saoudi

Using variational methods, we establish the existence of infinitely many solutions to an elliptic problem driven by a Choquard term and a singular nonlinearity. We further show tha…

The blow-up rate for a non-scaling invariant semilinear wave equations in higher dimensions

Mohamed Ali Hamza, Hatem Zaag

We consider the semilinear wave equation $\partial_{t}^{2} u - Δ u = f (u), (x, t) \in R^{N} \times [0, T), (1)$ with $f (u) = ∣ u ∣^{p - 1} u lo g^{a} (2 + u^{2})$ , where $p > 1$ and $a\in…

Radiation Shielding Properties of $N d_{0.6} S r_{0.4} M n_{1 - y} N i_{y} O_{3}$ Substitute with Different Concentrations of Nickle

M. Kh. Hamad, M. H. A. Mhareb, Y. S. Alajeramid +4

In this work, we investigate the effect of Ni concentration on several shielding properties of $N d_{0.6} S r_{0.4} M n_{1 - y} N i_{y} O_{3}$ (0.00 $\leq$ y $\leq$ 0.20) perovskite ceramic…
