Polynomialit{é} d'anneaux de repr{é}sentations modulaires projectives [PDF]
arXiv, 2017 Consider the Grothendieck group of finite type projective modular representations of the symmetric groups on n letters, or more generally, of its wreath product with a finite group. They form a graded group, with a product defined using induction. We show that the resulting graded ring is a polynomial ring.

Mixed Outcomes in Recombination Rates After Domestication: Revisiting Theory and Data
Molecular Ecology, EarlyView.ABSTRACT The process of domestication has altered many phenotypes. Selection on these phenotypes has long been hypothesised to indirectly select for increases in the genome‐wide recombination rate. This hypothesis is potentially consistent with theory on the evolution of the recombination rate, but empirical support has been unclear. We review relevant

Polynomiality of Grothendieck groups for finite general linear groups, Deligne-Lusztig characters, and injective unstable modules [PDF]
arXiv, 2019 Let K 0 (Fp GLn(Fp)-proj) denote the Grothendieck group of finitely generated pro-jective Fp GLn(Fp)-modules. We show that the algebra C $\otimes$ n$\ge$0 K 0 (Fp GLn(Fp)-proj) with multiplication given by induction functors, is a polynomial algebra. We explicit generators and their relation with Deligne-Lusztig characters.

Comparison of planted soil infiltration systems for treatment of log yard runoff [PDF]
, 2010 Treatment of log yard runoff is required to avoid contamination of receiving watercourses. The research aim was to assess if infiltration of log yard runoff through planted soil systems is successful and if different plant species affect the treatment

Concurrent anthropogenic stressors affect plant–soil systems with different plant diversity levels
New Phytologist, EarlyView.Summary Plant diversity strongly influences ecosystem functioning. Due to human activities, ecosystems are increasingly threatened by the co‐occurrence of numerous anthropogenic pressures, but how they respond to this multifaceted phenomenon is poorly documented, and what role plant diversity plays in this process has not been investigated so far. Here,

Intrinsic time lags in blazar flares and the search of Lorentz Invariance Violation signatures [PDF]
PoS(ICRC2017)611, 2017 Some Quantum Gravity models predict a violation of Lorentz invariance. Namely, the velocity of photons in vacuum could depend on their energies. One possibility for Lorentz Invariance Violation (LIV) searches is to look for energy-dependent delays in the arrival time of very high energy (VHE) photons coming from distant sources such as TeV emitting ...
