Cosets of Sylow p-subgroups and a Question of Richard Taylor [article]

Daniel Goldstein, Robert M. Guralnick
2012 arXiv   pre-print
We prove that for any prime p there exist infinitely many finite simple groups G with a coset xP of a Sylow p-subgroup P of G such that every element of xP has order divisible by p.  ...  John Thompson proved this for p=2 in 1967 answering a question of Lowell Paige. This result is used to answer a question of Richard Taylor on adequate representations.  ...  Guralnick was partially supported by the NSF grant DMS-1001962 and Simons Foundation fellowship 224965. Our method is similar to the one used by Thompson.  ...

No general relationship between mass and temperature in endothermic species

Kristina Riemer, Robert P Guralnick, Ethan P White
2018 eLife  
To test if Bergmann's rule can be extended to many species, Riemer, Guralnick, and White assessed the relationship between temperature and body mass for 952 bird and mammal species.  ...  In addition to other trait information, mass has recently been extracted and converted to a more usable form from Darwin Core formatted records published in VertNet (Guralnick et al., 2016) .  ...

Rational rigidity for F4(p)

Robert M. Guralnick, Frank Lübeck, Jun Yu
2016 Advances in Mathematics  
We prove the existence of certain rationally rigid triples in F_4(p) for good primes p (i.e., p>3), thereby showing that these groups occur as regular Galois groups over Q(t) and so also over Q.  ...  In the present paper we show that F 4 (p) occur as Galois groups over Q for all good primes p. In [7] , a similar result was proved by Guralnick and Malle for E 8 (p).  ...  (of the theorem) (1) Let x ∈ C 1 ∩ F 4 (p), y ∈ C 2 ∩ F 4 (p) and z ∈ C 3 ∩ F 4 (p).  ...

On the commuting probability of p-elements in a finite group [article]

Timothy C. Burness, Robert M. Guralnick, Alexander Moretó, Gabriel Navarro
2022 arXiv   pre-print
This bound is best possible in the sense that for each prime p there are groups with Pr_p(G) = (p^2+p-1)/p^3 and we classify all such groups.  ...  In this paper we prove that Pr_p(G) > (p^2+p-1)/p^3 if and only if G has a normal and abelian Sylow p-subgroup, which generalizes previous results on the widely studied commuting probability of a finite  ...  We now compute |C G (x) p | = (p 3 − p 2 )r p + p 2 , |G p | = (p 3 − p 2 )r p + (p 4 − p 3 )r p−1 + p 2 .

aTRAM 2.0: An Improved, Flexible Locus Assembler for NGS Data

Julie M Allen, Raphael LaFrance, Ryan A Folk, Kevin P Johnson, Robert P Guralnick
2018 Evolutionary Bioinformatics  
Massive strides have been made in technologies for collecting genome-scale data. However, tools for efficiently and flexibly assembling raw outputs into downstream analytical workflows are still nascent. aTRAM 1.0 was designed to assemble any locus from genome sequencing data but was neither optimized for efficiency nor able to serve as a single toolkit for all assembly needs. We have completely re-implemented aTRAM and redesigned its structure for faster read retrieval while adding a number of
more » ... key features to improve flexibility and functionality. The software can now (1) assemble single-or paired-end data, (2) utilize both read directions in the database, (3) use an additional de novo assembly module, and (4) leverage new built-in pipelines to automate common workflows in phylogenomics. Owing to reimplementation of databasing strategies, we demonstrate that aTRAM 2.0 is much faster across all applications compared to the previous version.
