Geographic variation in morphology of Northern Cardinals: possible application of Bergmann’s Rule?

open access: yesJournal of Field Ornithology, 2022
Geographic variation in morphological characteristics of a species can be influenced by environmental conditions. Bergmann’s rule states that endotherms inhabiting colder climates at higher latitudes are predicted to have larger body sizes.

Homotopy cardinality via extrapolation of Morava–Euler characteristics

open access: yesSelecta Mathematica, 2023
We answer a question of John Baez, on the relationship between the classical Euler characteristic and the Baez-Dolan homotopy cardinality, by constructing a unique additive common generalization after restriction to an odd prime p. This is achieved by ell-adically extrapolating to height n = -1 the sequence of Euler characteristics associated with the ...

Ultrafilters on 𝜔-their ideals and their cardinal characteristics [PDF]

open access: yesTransactions of the American Mathematical Society, 1999
For a free ultrafilter U \mathcal {U} on ω \omega we study several cardinal characteristics which describe part of the combinatorial structure of U \,\mathcal {U} . We provide various consistency results; e.g.

A Galvin–Hajnal theorem for generalized cardinal characteristics

open access: yesEuropean Journal of Mathematics, 2023
AbstractWe prove that a variety of generalized cardinal characteristics, including meeting numbers, the reaping number, and the dominating number, satisfy an analogue of the Galvin–Hajnal theorem, and hence also of Silver’s theorem, at singular cardinals of uncountable cofinality.
