Critical-exponent spectra and rank two inverse realization on biregular trees

Sanghoon Kwon

We study the critical-exponent, or equivalently entropy, spectrum arising from free type-preserving actions on the biregular tree $T_{r + 1, s + 1}$ . For an action with a nonem…

Exact renewal laws for minimal common-denominator profiles in simultaneous Laurent-series approximation

Sanghoon Kwon

Let $α_{1}, \dots, α_{r}$ be independent Haar-random fractional Laurent series over $F_{q}$ , and let $L_{r} (n)$ be the least coefficient length of a polynomial denominator that sim…

$K$ -spherical horospherical averages on the Nagao quotient: tree combinatorics and exact discrepancy

Sanghoon Kwon

Let $q$ be a prime power, $F = F_{q} ((t^{- 1}))$ , $G = SL_{2} (F)$ , $Γ = SL_{2} (F_{q} [t])$ , and $K = SL_{2} (F_{q} [[t^{- 1}]])$ , and let $U < G$ be…

Special periods and some non-tempered cases of the Gan-Gross-Prasad conjecture

Jaeho Haan, Sanghoon Kwon

In this paper, we establish a relationship between special periods and special L-values of automorphic representations of classical groups, and prove the non-tempered global Gan--G…

Zeta functions of geometrically finite graphs of groups

Soonki Hong, Sanghoon Kwon

In this paper, we explore the properties of zeta functions associated with infinite graphs of groups that arise as quotients of cuspidal tree-lattices, including all non-uniform ar…

The local converse theorem for quasi-split $O_{2 n}$ and $S O_{2 n}$

Jaeho Haan, Yeansu Kim, Sanghoon Kwon

Let $F$ be a non-archimedean local field of characteristic not equal to 2. In this paper, we prove the local converse theorem for quasi-split $Ø_{2 n} (F)$ and $\SO_{2n}(F)$, via the…
