    Higher genus open gromov witten theory

    It's a two part question about higher genus open gromov witten theory:
    What is the current status and how far are we from a general theory in higher genus?
    What are the directions that are being pursued or can be pursued?

    Failure of self-adjointness for the scaling generator in trace-formula models of...

    Let $\mathcal H = L^2(\mathbb{R}_+^\times, d^\times x)$, and let$$(Df)(x) = x \frac{d}{dx}f(x)$$denote the infinitesimal generator of the scaling action$$f(x) \mapsto f(e^t x).$$
    It is well known that:
    $D$ is not essentiallyself-adjoint on natural densedomains in $\mathcal H$,...

    Comparison of categories in HoTT book and Rezk types in simplicial HoTT

    In HoTT book we have definition of a category, consisting a groupoid as the core of category and Hom sets between objects. In simplicial HoTT, we have Rezk types modeling internal $\infty$-categories in any $\infty$-topos. My question is, can we define...

    Conjecture on the existence of non-trivial integer solutions to $A^4+B^4+C^4=2 n...

    I have been investigating the existence of non-trivial integer solutions to the Diophantine equation:$A^{4}+B^{4}+C^{4}=2n^{2}D^{4}$where $n$ is a square-free positive integer.
    Through extensive computational search (covering $n$ up to $1013$), I have found that this equation possesses extremely large primitive integer solutions for many values of $n$. For instance, when $n=101$, the smallest solution involves integers with...
