Reduced Products of Collapsing Algebras
$\mathop{\rm rp}\nolimits ({\mathbb B})$ denotes the reduced power ${\mathbb B}^ω/Φ$ of a Boolean algebra ${\mathbb B}$, where $Φ$ is the Fréchet filter $Φ$ on $ω$. We investigate iterated reduced powers ($\mathop{\rm rp}\nolimits ^0 ({\mathbb B})={\mathbb B}$ and $\mathop{\rm rp}\nolimits ^{n+1} ({\mathbb B} )=\mathop{\rm rp}\nolimits (\mathop{\rm rp}\nolimits ^n ({\mathbb B}))$) of collapsing algebras and our main intention is to classify the algebras $\mathop{\rm rp}\nolimits ^n (\math…

On solvability of a time-fractional semilinear heat equation, and its quantitative approach to the classical counterpart
We are concerned with the following time-fractional semilinear heat equation in the $N$-dimensional whole space ${\bf R}^N$ with $N \geq 1$. \[ {\rm (P)}_α\qquad \partial_t^αu -Δu = u^p,\quad t>0,\,\,\, x\in{\bf R}^N, \qquad u(0) = μ\quad \mbox{in}\quad {\bf R}^N, \] where $\partial_t^α$ denotes the Caputo derivative of order $α\in (0,1)$, $p>1$, and $μ$ is a nonnegative Radon measure on ${\bf R}^N$. The case $α=1$ formally gives the Fujita-type equation (P)$_1$ \ $\partial_…

Anyone know, is there a dentist anywhere in the UK where they're doing science-based covid precautions?
Everyone in FFP3s or better, all the time?
(not only for so-called "aerosol-generating procedures")
air filters with a capacity high enough to turn over the room's air in between patients?
staff testing?
Even if too far away from me, I'd like to at least be able to say to the rest of them that it exists and they _could_ do the same.
Boosts welcome.
