Published in 2018 at "Mathematische Nachrichten"

DOI: 10.1002/mana.201700467

Abstract: Let r be a positive integer. Assume Greenberg's conjecture for some totally real number fields, we show that there exists an infinite family of imaginary cyclic number fields F over the field of rational number… read more here.

Published in 2020 at "Mediterranean Journal of Mathematics"

DOI: 10.1007/s00009-019-1469-9

Abstract: We prove the Brannan conjecture for particular values of the parameter. The basic tool of the study is an integral representation published in a recent work (Barnard et al., in Proc Am Math Soc 143(5):2117–2128,… read more here.

Published in 2018 at "Archiv der Mathematik"

DOI: 10.1007/s00013-018-1258-x

Abstract: We show that the Faber–Krahn inequality implies Pólya’s conjecture for eigenvalues $$\lambda _{k}$$λk of the Dirichlet Laplacian in $$\mathbb {R}^n$$Rn up to $$k = \lfloor b(n) \rfloor $$k=⌊b(n)⌋, where b(n) is a function with exponential… read more here.

Published in 2020 at "Archiv der Mathematik"

DOI: 10.1007/s00013-020-01530-8

Abstract: We work with a conjecture on the BNS-invariant of Artin groups stated by Almeida and Kochloukova. We show that the class of Artin groups that satisfy this conjecture is closed under finite graph products. As… read more here.

Published in 2018 at "Journal of Fourier Analysis and Applications"

DOI: 10.1007/s00041-017-9524-z

Abstract: Although the “hot spots” conjecture was proved to be false on some classical domains, the problem still generates a lot of interests on identifying the domains that the conjecture hold. The question can also be… read more here.

Published in 2019 at "Mathematische Annalen"

DOI: 10.1007/s00208-019-01926-0

Abstract: It is shown that the strong Atiyah conjecture and the Lück approximation conjecture in the space of marked groups hold for locally indicable groups. In particular, this implies that one-relator groups satisfy both conjectures. We… read more here.

Published in 2018 at "Mathematische Annalen"

DOI: 10.1007/s00208-019-01940-2

Abstract: We develop Denef–Loeser’s motivic integration to an equivariant version and use it to prove the full integral identity conjecture for regular functions. In comparison with Hartmann’s work, the equivariant Grothendieck ring defined in this article… read more here.

Abstract: In this article, we study the Beilinson-Bloch-Kato conjecture for motives corresponding to the Rankin-Selberg product of conjugate self-dual automorphic representations, within the framework of the Gan-Gross-Prasad conjecture. We show that if the central critical value… read more here.
