Let $(C,0)$ be a reduced planar curve singularity over $\mathbf{k} = \mathbb{C}$, let $\delta$ be its $\delta$-invariant, and let $n_h(C,0)$, $0\leq h\leq\delta$, be the BPS invari…

Let $(C,0)$ be a planar curve singularity, and let $L(q,t,0)$ be the specialization at $a=0$ of its Hilbert $L$-function. A $t$-zero is a complex number $\xi$ such that…

Let $(C,0)$ be a planar curve singularity. Let $L(q,t,a)$ be its Hilbert $L$-function and let $\mathrm{H}^{\mathrm{mot}}(q,t,a)$ be its normalized motivic superpolynomial. Cheredni…
