We will present some recent progress on two problems in minimal surface theory posed by S. T. Yau in 1982. In particular, we will discuss the existence of infinitely many closed minimal hypersurfaces in a closed Riemannian manifold and the existence of four closed minimal two-spheres in a Riemannian three-sphere.

The COVID-19 pandemic still poses a continuous threat due to the emergence of multiple strains. Insights into the virus infection dynamics within a host and virus transmission dynamics between hosts are essential for designing effective control strategies. In the first part of this talk, I will present mathematical models describing how the virus spreads within a single host. In particular, we implement viral load data from ferrets (animal models) to estimate critical parameters related to SARS CoV-2 infection and formulate the risk of transmission and generation time distribution. In the second part, I will discuss between-hosts models for the transmission dynamics of COVID-19 in a community. We apply our models to the unique datasets from Nepal, which shares open borders with India, one of the most COVID-19-impacted countries in the world. I will demonstrate how our data-driven models can provide vital information for developing control strategies for both within-host and between-host scales.

The Central Limit Theorem of
probability represented in the PDE setting can be described as follows: consider the heat equation on \(\mathbb^n\),
\[
\partial_u(t,x)\,=\,\Delta_u(t,x),
\quad
u(0,x)\,=\,f(x),
\]
with initial data $f \in L^1(\mathbb^n)$.
Denote by $M = \int_f(x)\, dx$ the mass and by $h_t(x) = (4\pi t)^e^{-\frac{\|x\|^2}}$
the heat kernel. Then the following asymptotics are known to hold in $L^p(\mathbb^n)$, for all $1 \leq p \leq \infty$:
$$
\lim_ t^\|u(t,\cdot)-M\,h_t\|_=0.
$$


Analogous heat asymptotics may or may not hold on Riemannian manifolds. Our aim is to discuss noncompact symmetric spaces $G/K$ of arbitrary rank,
generalizing earlier results of J.L. Vzquez on real hyperbolic spaces.
More precisely, we discuss the heat equation related to the Laplace-Beltrami operator and to the distinguished Laplacian. In the first
case, if the data is bi-$K$-invariant, the convergence is true, but unlike the Euclidean case, if this symmetry on initial data is removed, the convergence may fail. In the case of the distinguished Laplacian, we observe phenomena
resembling to the Euclidean setting.
