Orbits and attainable Hamiltonian diffeomorphisms of mechanical Liouville equations
We study the approximate controllability problem for Liouville transport equations along a mechanical Hamiltonian vector field. Such PDEs evolve inside the orbit $$\mathcal{O}(ρ_0):=\left\{ρ_0\circ Φ\mid Φ\in {\rm DHam}(T^*M)\right\},\quad ρ_0\in L^r(T^*M,\R), \quad r\in[1,\infty),$$ where $ρ_0$ is the initial density and ${\rm DHam}(T^*M)$ is the group of Hamiltonian diffeomorphisms of the cotangent bundle manifold $T^*M$. The approximately reachable densities from $ρ_0$ are thus contai…

We refine the cycle-walk (Fourier) template of Gnacik and the author to quantify when a~$δ$-Sule\uımanova spectrum $(1,λ_2,\dots,λ_n)$ (with $λ_j\le 0$) is realised by a symmetric doubly stochastic matrix. For the canonical cycle basis we compute the \emph{exact} size-dependent threshold \[ δ_n \;=\; 1-\frac{1}{2\cos^2\!\Big(\fracπ{4n}ρ(n)\Big)}, \quad ρ(n)\in\{0,1,2,4\}\ \text{determined by } n\bmod 8, \] which improves $1/2$ if and only if $8\nmid n$; we also prove sharpness for that…

Tight bounds for judicious 3-partitions of graphs
In this paper, we show that every graph with $m$ edges admits a 3-partition such that \[ \max_{1 \leq i \leq 3} e(V_i) \leq \frac{m}{9} + \frac{1}{9}h(m) \quad \text{and} \quad e(V_1, V_2, V_3) \geq \frac{2}{3}m + \frac{1}{3}h(m), \] where $h(m) = \sqrt{2m + 1/4} - 1/2$. This answers a problem of Bollobás and Scott affirmatively. We also solve several related problems of Bollobás and Scott. All of our results are tight.

RARO: Reliability-aware Conversion with Enhanced Read Performance for QLC SSDs
Quad-level cell (QLC) flash offers significant benefits in cost and capacity, but its limited reliability leads to frequent read retries, which severely degrade read performance. A common strategy in high-density flash storage is to program selected blocks in a low-density mode (SLC), sacrificing some capacity to achieve higher I/O performance. This hybrid storage architecture has been widely adopted in consumer-grade storage systems. However, existing hybrid storage schemes typically focus on …

Greenś Mapping and Julia Sets
In March 1999, the first named author (Binder) posed the problem of showing that a ``good direction'' $ψ\in [0,2]$ exists, for any Green's mapping $T:H\rightarrow\tilde Ω$, i.e., \begin{equation}\label{binder} \int\limits_0\limits^{1} |T''(re^{iπψ})|dr <\infty, \quad\text{ for at least one } \quad ψ\in [0,2]. \end{equation} Presently this problem is open even in the special case where $\partial Ω$ is a uniformly perfect subset of the real line. In this paper we obtain a posi…

Liouville theorem for the inequality $Δ_m u+f(u)\leq 0$ on Riemannian manifolds
In this paper, we study the quasilinear inequality $ Δ_m u+f(u)\leq 0$ on a complete Riemannian manifold, where \begin{align*} m>1,α>m-1 \quad and \quad f(t)> 0,αf(t)-tf^{'}(t)\geq 0, \forall t>0. \end{align*} If for some point $x_0$ and large enough $r$, \begin{align*} vol B_r(x_0)\leq C r^p ln^q r, \end{align*} where $p=\frac{mα}{α-(m-1)},q=\frac{m-1}{α-(m-1)}$ and $B_r(x_0) $ is a geodesic ball of radius $r$ centered at $x_0$, then the inequality possesses no positive weak solution.

Weak Existence and Uniqueness for Super-Brownian Motion with Irregular Drift
We establish weak existence and uniqueness for random field solutions of the one-dimensional SPDE \[ d_tX_t = \frac{1}{2}ΔX_t +h(X_t)+ \sqrt{X_t}\dot{W}, \quad t\geq 0,\] where $\dot{W}$ is space-time white noise and $h$ is a bounded drift with $h(0)\geq 0$. The proof relies on an extension of the duality relation of the super-Brownian motion, which allows us to treat a broad class of admissible drifts, including functions that are non-Lipschitz or discontinuous at zero.

We generalize the concept of local level sets and find that the expected number of local level sets contained in a level set $L_r(y)$, with $y$ chosen at random, is $1 + 1/r$ for every even integer $r \geq 2$.

Superior Highly Composite Numbers and the Explicit Upper Bound of Generalized Divisor Functions
For $k\geq 2$, we give a detailed exposition of the superior $k$-highly composite numbers. We then consider the function \[f_k(n)=\frac{\log d_k(n)\log\log n}{\log k\log n},\quad n\geq 3\] which has a maximum value $λ(k)$ at a superior $k$-highly composite number. We develop an efficient algorithm to compute $λ(k)$ and the positive integer $N_{\max}(k)$ where $f_k$ achieves the value $λ(k)$. The results for $2\leq k\leq 100$ are tabled.

On the vanishing viscosity limit of Hamilton-Jacobi equations with nearly optimal discount
In this paper, we establish the convergence of solutions to the viscous Hamilton-Jacobi equation (with a Tonelli Hamiltonian): \[ λu +H(x, du)=\varepsilon(λ)Δu,\quad λ>0 \] as $λ\rightarrow 0_+$, once the modulus $\varepsilon(λ)$ satisfies $\varlimsup_{λ\rightarrow 0_+}\varepsilon(λ)/λ=0$. Such an exponent of $\varepsilon(λ)$ is nearly optimal in the convergence.
