Monochromatic trees in random tournaments

AbstractWe prove that, with high probability, in every 2-edge-colouring of the random tournament on n vertices there is a monochromatic copy of every oriented tree of order $O(n{\rm{/}}\sqrt {{\rm{log}} \ n} )$. This generalizes a result of the first, third and fourth authors, who proved the same statement for paths, and is tight up to a constant factor.

Oxandrolone for growth hormone-treated girls aged up to 18 years with Turner syndrome.

The final adult height of untreated girls aged up to 18 years with Turner syndrome (TS) is approximately 20 cm shorter compared with healthy females. Treatment with growth hormone (GH) increases the adult height of people with TS. The effects of adding the androgen, oxandrolone, in addition to GH are unclear. Therefore, we conducted this systematic review to investigate the benefits and harms of oxandrolone as an adjuvant therapy for people with TS treated with GH. To assess the effects of oxandrolone on growth hormone-treated girls aged up to 18 years with Turner syndrome. We searched CENTRAL, MEDLINE, Embase, the ICTRP Search Portal and ClinicalTrials.gov. The date of the last search was October 2018. We applied no language restrictions. We included randomised controlled clinical trials (RCTs) that enrolled girls aged up to 18 years with TS who were treated with GH and oxandrolone compared with GH only treatment. Three review authors independently screened titles and abstracts for relevance, selected trials, extracted data and assessed risk of bias. We resolved disagreements by consensus, or by consultation with a fourth review author. We assessed trials for overall certainty of the evidence using the GRADE instrument. We included six trials with 498 participants with TS, 267 participants were randomised to oxandrolone plus GH treatment and 231 participants were randomised to GH only treatment. The individual trial sample size ranged between 22 and 133 participants. The included trials were conducted in 65 different paediatric endocrinology healthcare facilities including clinics, centres, hospitals and academia in the USA and Europe. The duration of interventions ranged between 3 and 7.6 years. The mean age of participants at start of therapy ranged from 9 to 12 years. Overall, we judged only one trial at low risk of bias in all domains and another trial at high risk of bias in most domains. We downgraded the level of evidence mainly because of imprecision (low number of trials, low number of participants or both). Comparing oxandrolone plus GH with GH only for final adult height showed a mean difference (MD) of 2.7 cm in favour of oxandrolone plus GH treatment (95% confidence interval (CI) 1.3 to 4.1; P < 0.001; 5 trials, 270 participants; moderate-quality evidence). The 95% prediction interval ranged between 0.3 cm and 5.1 cm. For adverse events, we based our main analysis on reliable date from two trials with overall low risk of bias. There was no evidence of a difference between oxandrolone plus GH and GH for adverse events (RR 1.81, 95% CI 0.83 to 3.96; P = 0.14; 2 trials, 170 participants; low-quality evidence). Six out of 86 (18.6%) participants receiving oxandrolone plus GH compared with 8/84 (9.5%) participants receiving GH only reported adverse events, mainly signs of virilisation (e.g. deepening of the voice). One trial each investigated the effects of treatments on speech (voice frequency; 88 participants), cognition (51 participants) and psychological status (106 participants). The overall results for these comparisons were inconclusive (very low-quality evidence). No trial reported on health-related quality of life or all-cause mortality. Addition of oxandrolone to the GH therapy led to a modest increase in the final adult height of girls aged up to 18 years with TS. Adverse effects identified included virilising effects such as deepening of the voice, but reporting was inadequate in some trials.

Noncommutative Knörrer periodicity and noncommutative Kleinian singularities

We establish a version of Knörrer's Periodicity Theorem in the context of noncommutative invariant theory. Namely, let A be a left noetherian AS-regular algebra, let f be a normal and regular element of A of positive degree, and take B=A/(f). Then there exists a bijection between the set of isomorphism classes of indecomposable non-free maximal Cohen-Macaulay modules over B and those over (a noncommutative analog of) its second double branched cover (B#)#. Our results use and extend the study of twisted matrix factorizations, which was introduced by the first three authors with Cassidy. These results are applied to the noncommutative Kleinian singularities studied by the second and fourth authors with Chan and Zhang.

On well-filtered reflections of T0 spaces

Following Ershov's method of constructing the d-completion of T0 spaces, we give a direct construction of the well-filtered reflection of T0 spaces. Also, we obtain an elegant characterization of well-filtered spaces using KF-sets. We then show that a product of a family of T0 spaces is well-filtered iff each factor space is well-filtered. Finally, we obtain that the well-filtered reflection of a product of a finite family of T0 spaces is the product of the well-filtered reflections of all factor spaces. A common theme is that KF-sets, introduced by the first and the fourth authors, function prominently in all of the above proofs.

Progress towards a nonintegrality conjecture

Given $$r \in \mathbb {N}$$ , define the function $$S_{r}:\mathbb {N} \rightarrow \mathbb {Q}$$ by In 2015, the second author conjectured that there are infinitely many $$r \in \mathbb {N}$$ such that $$S_{r}(n)$$ is nonintegral for all $$n \geqslant 1$$ , and proved that $$S_{r}(n)$$ is not an integer for $$r \in \{2,3,4\}$$ and for all $$n \geqslant 1$$ . In 2016, Florian Luca and the second author raised a stronger conjecture that for any $$r \geqslant 1$$ , $$S_{r}(n)$$ is nonintegral for all $$n \geqslant 1$$ . They proved that $$S_{r}(n)$$ is nonintegral for $$r \in \{5,6\}$$ and that $$S_{r}(n)$$ is not an integer for any $$r \geqslant 2$$ and $$1 \leqslant n \leqslant r-1$$ . In particular, for all $$r \geqslant 2$$ , $$S_{r}(n)$$ is nonintegral for at least $$r-1$$ values of n. In 2018, the fourth author gave sufficient conditions for the nonintegrality of $$S_{r}(n)$$ for all $$n \geqslant 1$$ , and derived an algorithm that sometimes determines such nonintegrality; along the way he proved that $$S_{r}(n)$$ is nonintegral for $$r \in \{7,8,9,10\}$$ and for all $$n \geqslant 1$$ . By improving this algorithm we prove the conjecture for $$r\leqslant 22$$ . Our principal result is that $$S_r(n)$$ is usually nonintegral in that the upper asymptotic density of the set of integers n with $$S_r(n)$$ integral decays faster than any fixed power of $$r^{-1}$$ as r grows.

Estimates for the {bar{partial }}-Equation on Canonical Surfaces

We study the solvability in L^p of the {bar{partial }}-equation in a neighborhood of a canonical singularity on a complex surface, a so-called du Val singularity. We get a quite complete picture in case p=2 for two natural closed extensions {bar{partial }}_s and {bar{partial }}_w of {bar{partial }}. For {bar{partial }}_s we have solvability, whereas for {bar{partial }}_w there is solvability if and only if a certain boundary condition (*) is fulfilled at the singularity. Our main tool is certain integral operators for solving {bar{partial }} introduced by the first and fourth author, and we study mapping properties of these operators at the singularity.

(q,t)-Catalan numbers: gamma expansions, pattern avoidances, and the (−1)-phenomenon

The aim of this paper is two-fold. We first prove several new interpretations of a kind of (q,t)-Catalan numbers along with their corresponding γ-expansions using pattern avoiding permutations. Secondly, we give a complete characterization of certain (−1)-phenomenon for each subset of permutations avoiding a single pattern of length three, and discuss their q-analogues utilizing the newly obtained q-γ-expansions, as well as the continued fraction of a quint-variate generating function due to Shin and the fourth author. Moreover, we enumerate the alternating permutations avoiding simultaneously two patterns, namely (2413,3142) and (1342,2431), of length four, and consider such (−1)-phenomenon for these two subsets as well.
