Conjugacy classes of Renner monoids
No full textAbstractIn this paper we describe conjugacy classes of a Renner monoid R with unit group W, the Weyl group. We show that every element in R is conjugate to an element ue where u∈W and e is an idempotent in a cross section lattice. Denote by W(e) and W⁎(e) the centralizer and stabilizer of e∈Λ in W, respectively. Let W(e) act by conjugation on the set of left cosets of W⁎(e) in W. We find that ue and ve (u,v∈W) are conjugate if and only if uW⁎(e) and vW⁎(e) are in the same orbit. As consequences, there is a one-to-one correspondence between the conjugacy classes of R and the orbits of this action. We then obtain a formula for calculating the number of conjugacy classes of R, and describe in detail the conjugacy classes of the Renner monoid of some J-irreducible monoids.We then generalize Munn conjugacy on a rook monoid to any Renner monoid and show that Munn conjugacy coincides with semigroup conjugacy, action conjugacy, and character conjugacy. We also show that the number of inequivalent irreducible representations of R over an algebraically closed field of characteristic zero equals the number of Munn conjugacy classes in R
A dated phylogeny and collection records reveal repeated biome shifts in the African genus Coccinia (Cucurbitaceae)
No full textBackground: Conservatism in climatic tolerance may limit geographic range expansion and should enhance the effects of habitat fragmentation on population subdivision. Here we study the effects of historical climate change, and the associated habitat fragmentation, on diversification in the mostly sub-Saharan cucurbit genus Coccinia, which has 27 species in a broad range of biota from semi-arid habitats to mist forests. Species limits were inferred from morphology, and nuclear and plastid DNA sequence data, using multiple individuals for the widespread species. Climatic tolerances were assessed from the occurrences of 1189 geo-referenced collections and WorldClim variables.
Results: Nuclear and plastid gene trees included 35 or 65 accessions, representing up to 25 species. The data revealed four species groups, one in southern Africa, one in Central and West African rain forest, one widespread but absent from Central and West African rain forest, and one that occurs from East Africa to southern Africa. A few individuals are differently placed in the plastid and nuclear (LFY) trees or contain two ITS sequence types, indicating hybridization. A molecular clock suggests that the diversification of Coccinia began about 6.9 Ma ago, with most of the extant species diversity dating to the Pliocene. Ancestral biome reconstruction reveals six switches between semi-arid habitats, woodland, and forest, and members of several species pairs differ significantly in their tolerance of different precipitation regimes.
Conclusions: The most surprising findings of this study are the frequent biome shifts (in a relatively small clade) over just 6 - 7 million years and the limited diversification during and since the Pleistocene. Pleistocene climate oscillations may have been too rapid or too shallow for full reproductive barriers to develop among fragmented populations of Coccinia, which would explain the apparently still ongoing hybridization between certain species. Steeper ecological gradients in East Africa and South Africa appear to have resulted in more advanced allopatric speciation there

The Hamiltonian is based on the MORBID Hamiltonian developed by which itself is based on the Hougen-Bunker-Johns . We determine the eigenfunctions and eigenvalues of this Hamiltonian in a variational manner, and the computer program we have developed is called RENNER; we have used RENNER to calculate the rovibronic energies of and other molecules. As well as calculating rovibronic energies from potential energy surfaces we are able to calculate intensities from dipole moment surfaces, and we can simulate spectra that involve electronic states subject to the Renner-Teller effect. Although there is a breakdown of the Born-Oppenheimer approximation one can still understand the situation using potential energy curves and dipole moment surfaces, but the shapes of the potential energy curves and dipole moment surfaces depend on the value of the rotational quantum number . This will be explained using our results for the molecule as an $example^{e}.
Lejeunea tumida Mitten 1855

(lectotype fide Grolle (1982): NY, isolectotypes: MPN, WELT!). The name Lejeunea tumida has been misapplied to a range of Australian Lejeunea species, including L. cuspidistipula (Stephani 1896: 88) Stephani ex Watts (1902: 493), L. drummondii Taylor (1846: 400), L. sinclairii Spruce non Mitt. auct. and L. sordida. The presence of L. tumida in Australia was considered dubious by Renner et al. (2010), but the species was not explicitly rejected because all material forming the basis of early records had not been investigated. Recent examination shows that early identifications of Australian material as Lejeunea tumida by Rodway and Stephani in the herbaria FH, BM and G are all referable to other species. Lejeunea tumida can therefore be rejected from the Australian flora with confidence. It, and all other members of the species group formerly included within it [L. colensoana (Stephani 1896: 132) Renner in Renner et al. (2010: 455), L. oracola Renner in Renner et al.

Relational Analysis of the Frauchiger–Renner Paradox and Interaction-Free Detection of Records from the Past
No full textWe present an analysis of the Frauchiger–Renner Gedankenexperiment from the point of view of the relational interpretation of quantum mechanics. Our analysis shows that the paradox obtained by Frauchiger and Renner disappears if one rejects promoting one agent’s certainty to another agent’s certainty when it cannot be validated by records from the past. A by-product of our analysis is an interaction-free detection scheme for the existence of such records.Analysi
