Saddle solutions for the fractional Choquard equation
- MathematicsZeitschrift für angewandte Mathematik und Physik
- 2022
(−∆)u+ u = (Kα ∗ |u|)|u|u, x ∈ R where s ∈ (0, 1), N ≥ 3 and Kα is the Riesz potential with order α ∈ (0, N). For every Coxeter group G with rank 1 ≤ k ≤ N and p ∈ [2, N+α N−2s ), we construct a…
Saddle solutions for the Choquard equation with a general nonlinearity

In the spirit of Berestycki and Lions, we prove the existence of saddle type nodal solutions for the Choquard equation −∆u+ u = ( Iα ∗ F (u) ) F ′(u) in R where N ≥ 2 and Iα is the Riesz potential of…
Topological shadows and complexity of islands in multiboundary wormholes

Recently, remarkable progress in recovering the Page curve of an evaporating black hole (BH) in Jackiw-Teitelboim gravity has been achieved through use of Quantum Extremal surfaces (QES).…
Coxeter groups, the Davis complex, and isolated flats
- Mathematics
- 2019
Coxter groups arose as a natural generalization of reflection groups. J. Tits defined them in a simple way using generators and relations, that is, using a group presentation W ∼= 〈S | R〉. Coxeter…
Quasi-isometric rigidity of a class of right-angled Coxeter groups
- MathematicsProceedings of the American Mathematical Society
- 2019
We establish quasi-isometric rigidity for a class of right-angled Coxeter groups. Let $\Gamma_1,\Gamma_2$ be joins of finite generalized thick $m$-gons with $m\geq 3$. We show that the corresponding…

W is finite then there is a point w ∈ W and a spherical subset T ⊆ S
We will need the following "Cartan-Hadamard Theorem for CAT(0) spaces" due to Gromov: Bibliography
The "conjugacy problem" for W is decidable. (This question still remains open for the "isomorphism problem
