We give a brief overview of the life and combinatorics Jeff Remmel, mathematician with successful careers in both logic combinatorics.

To an extent, the 1966 congress was a hole in iron curtain. At least that how young Soviet mathematician saw it.

The famous Pósa conjecture states that every graph of minimum degree at least 2n/3 contains the square of a Hamilton cycle. This has been proved for large n by Komlós, Sarközy and Szemerédi. Here we prove that if p ≥ n−1/2+ε, then asymptotically almost surely, the binomial random graph Gn,p contains the square of a Hamilton cycle. This provides an ‘approximate threshold’ for the property in the...

Mathematician Ralph Abraham recounts memories of Dave Loye, Riane Eisler, Ervin Laszlo, the General Evolution Research Group, and their 37-year partnership.

The term ‘bioeconomy’, or, more precisely, ‘bioeconomics’ was initially introduced in the 1970s by Nicholas Georgescu-Roegen, a Romanian mathematician and economist, who connected physics econo...
