powers (with $i\\in \\{j\,j+1\,\\ldots \,s\\}$) if and only if the series
$1/k_1+1/k_2+\\ldots $ diverges. We describe recent work joint with J\\"or

DESCRIPTION:Title: Large gaps between sums of two squarefull numbers\nby Sergei Konyagi
n (Steklov Institute\, Moscow\, Russia) as part of Combinatorial and addit
ive number theory (CANY 2023)\n\nLecture held in Room 4102 in CUNY Grad Ce
nter.\n\nAbstract\nA positive integer $n$ is called squarefull or powerful
if in its factorization\n$n = p_1^{\\alpha_1}\\dots p_r^{\\alpha_r}$ we h
ave $\\alpha_i\\ge2$ for all $i$.\nWe consider that $0$ is also a squarefu
ll number.\nThus\, a number is squarefull if and only if it can be represe
nted as\n$n = a^2b^3$ for some $a\,b\\in{\\Bbb Z}_+$.\n\nLet $W$ be the se
t of all sums of two squarefull numbers. Blomer (2005) proved that\n$$ W(x
):= |W\\cap[1\,x]| = \\frac x{(\\log x)^{\\alpha+o(1)}}\\quad(x\\to\\inft
y)\,$$\nwhere $\\alpha = 1 - 2^{-1/3} = 0.20\\dots$.\n\nAs suggested by Sh
parlinski\, we study large gaps between elements of $W$. \nNamely\, for $x
> 1$ define $M(x)$ as the length of the largest subinterval of $[1\,x]$\n
without elements of $W$. Blomer's result implies that $M(x) \\ge (\\log x)
^{\\alpha+o(1)}$\nas $x\\rightarrow \\infty$ since the largest gap is at l
east as large as the average gap. We improve\nthis estimate.\n\n Theorem:
For $x\\ge3$ we have $M(x)\\ge c(\\log x)/(\\log\\log x)^2$ where $c>0$\ni
s an absolute constant.\n\nJoint work with Alexander Kalmynin.\n

DESCRIPTION:Title: Explicit bounds on sums of the M\\" obius functions\nby Harald Helfg
ott (Universit\\" at G\\" ottingen\, Germany and CNRS\, France) as part of
Combinatorial and additive number theory (CANY 2023)\n\nLecture held in R
oom 4102 in CUNY Grad Center.\n\nAbstract\nLet $M(x)$ be the Mertens funct
ion $M(x) = \\sum_{n\\leq x} \\mu(n)$. Most of us are used to thinking of
the problem of estimating $M(x)$ as being essentially equivalent to the pr
oblem of estimating the number of primes up to $x$ (i.e.\, the Prime Numbe
r Theorem). If we want explicit bounds\, however\, the problem of bounding
$M(x)$ becomes by far the harder of the two problems. The main reason is
that\, while the residue of $- \\zeta'(s)/\\zeta(s)$ at a zero of $\\zeta(
s)$ is just the order of the zero\, we do not have a good way to control t
he residues of $1/\\zeta(s)$.\n(There are bounds for $1/\\zeta(s)$ inside
the zero-free region\, but their constants are very large.)\n\nUp to now\,
the best bounds on $M(x)$ have been either (a) based on elementary method
s that amount to delicate refinements of Chebyshev-Mertens\, or (b) based
on iterative processes that combine (a) with explicit versions of PNT. (Th
e best results of these two kinds to date are due to Daval (unpublished) a
nd Ramar\\' e\, respectively.) The same is true of sums of the form $m(x)
= \\sum_{n\\leq x} \\mu(n)/n$\, $\\check{m}(x) = \\sum_{n\\leq x} \\mu(n)
\\log(x/n)/n$\, etc.\, which appear often in analytic number theory.\n\nWe
give considerably stronger bounds on $M(x)$\, $m(x)$ and $\\check{m}(x)$
by means of an analytic approach based on mean-value theorems. \n\nJoint w
ork with Andr\\' es Chirre.\n

ad Center.\n\nAbstract\nIn consecutive notebook entries\, Ramanujan gave a
symptotic approximations to the exponential function and the exponential i
ntegral. The asymptotic expansion coefficients seem to agree up to an alte
rnating sign\, as we conjectured in an earlier paper. We establish this hi
dden link with a combinatorial proof that involves Stirling numbers\, seco
nd-order Eulerian numbers\, modifications of both of these\, and Stirling'
s approximation to the gamma function. An analytic second proof has also b
een provided by a referee. It is not yet clear if this result is an oddity
or part of a broader picture.\n
