The 3/5-conjecture for weakly $S (K_{1, 3})$ -free forests

Simon Schmidt

The $3/5$ -conjecture for the domination game states that the game domination numbers of an isolate-free graph $G$ on $n$ vertices are bounded as follows: $γ_{g} (G) \leq \frac{3 n}{5}$ a…

New examples of cylindrical Fano fourfolds

Yuri Prokhorov, Mikhail Zaidenberg

We construct new families of smooth Fano fourfolds with Picard rank 1, which contain cylinders, i.e., Zariski open subsets of form $Z \times A^{1}$ , where $Z$ is a quasiprojective var…

Collision of almost parallel vortex filaments

Valeria Banica, Erwan Faou, Evelyne Miot

We investigate the occurrence of collisions in the evolution of vortex filaments through a system introduced by Klein, Majda and Damodaran [KMD95] and Zakharov [Z88,Z99]. We first…

Automorphism Groups of Configuration Spaces and Discriminant Varieties

Vladimir Lin, Mikhail Zaidenberg

The configuration space $C^{n} (X)$ of an algebraic curve $X$ is the algebraic variety consisting of all $n$ -point subsets $Q \subset X$ . We describe the automorphisms of $\m…

The Ring of Support-Classes of $SL_2 (F_q)$

Roland Bacher

We introduce and study a subring $SC$ of $Z [SL_2 (F_q)]$ obtained by summing elements of $SL_2 (F_q)$ according to their suppo…

Algebra properties for Besov spaces on unimodular Lie groups

Joseph Feneuil

We consider the Besov space $B_{α}^{p, q} (G)$ on a unimodular Lie group $G$ equipped with a sublaplacian $Δ$ . Using estimates of the heat kernel associated with $Δ$ , we give several c…
