Describing all bi-orderings on Thompson’s group F
(2009)
We describe all possible ways of bi-ordering Thompson’s group F: its space of bi-orderings is
made up of eight isolated points and four canonical copies of the Cantor set.

Cohomology and graded Witt group kernels for extensions of degree four in characteristic two
(2016)
In earlier work the authors determined the graded Witt kernel GW(q)(E/F) = ker(GW(q)F -> GW(q)E) when E/F is a biquadratic extension in characteristic 2 by calculating the cohomological kernel H-2*(E/F) = ker(H-2*F -> ...
Synthesis of New Pentaerythritol-Based Gemini Surfactants
(Georg Thieme Verlag Kg, 2001-06)
New dimeric or gemini surfactants bearing double-chain with two or four sulfonate groups, and quadruple-chain with four sulfonate groups, were prepared from pentaerythritol in good overall yields. All these surfactants ...
Bioacoustics of four Scinax species and a review of acoustic traits in the Scinax catharinae species group (Amphibia: Anura: Hylidae)
