Let $n$ be the sample size, and let $(a_0,a_1)$ denote the MA(1) parameters. Restrict attention to solutions satisfying $\operatorname{Re}(a_0)>0$. Restricted MA(1) ML-degree conje…

Let $\Delta$ be a reflexive simplex, and let $\mathrm{mldeg}(\Delta)$ and $\mathrm{deg}(\Delta)$ denote its maximum likelihood degree and degree, respectively, under the standard s…

Let $X\subseteq\mathbb{P}^n$ be a projective variety, and let $\pi_n:X\dashrightarrow\mathbb{P}^{n-1}$ be projection from the center $(0:\cdots:0:1)$. Assume that the projection ma…

Let $X\subseteq\mathbb{P}^n$ and $X\cap\{p_n=0\}$ be reduced and irreducible, and assume that neither is contained in its respective hyperplane arrangement $\mathcal{H}$. Let…

Let $X\subseteq\mathbb{P}^n$ be a projective variety not contained in the hyperplane arrangement $\mathcal{H}$. Let $B_X(p,u)$ be its ML bidegree and $S_X(p,u)$ its sectional ML de…
