Otto Blumenthal (1876-1944) in retrospect
This paper treats in detail the life and work of Otto Blumenthal, one of the most tragic figures of the 188 emigré mathematicians from Germany and the Nazi-occupied continent. Blumenthal, the first doctoral student of David Hilbert, was crucial in the publication and communication system of German mathematics between the two World Wars. There has been an unusual revival of interest in his mathe...
متن کاملThe Blumenthal Conjecture
The following conjecture was posed by Hayman in his collection of research problems [6]. Let f1(z), f2(z) be entire functions. Is it true that if (1) M(r, f1) = M(r, f2) , 0 < r < ∞, then f1(z), f2(z) are equivalent apart from rotations and reflections? Hayman suggested that the corresponding problem for polynomials (of degree higher than about 6) is also open but such results have yet to be pu...

This study mainly addresses two questions: (i) what is the verse grammar that governs the modern speaker’s scansion of classical Chinese verse lines? (ii) how can his apparently intuitive judgment of metrical harmony of verse lines be accounted for in a principled way? For the first question, we have argued that the modern verse grammar represents the coexistence of five minimally different sub...
متن کاملOtto Loewi
The end of the 19th century was the starting point of many discoveries in the field of the neurophysiology. At that time, only basic technical approaches were available, and new discoveries depended on few results and lots of deductions. Furthermore, the scientific community was often debating on theoretical speculations and was often divided. I have chosen to present a German neurophysiologist...
متن کاملWalrasian Economics in Retrospect
Two basic tenets of the Walrasian model, behavior based on self-interested exogenous preferences and complete and costless contracting have recently come under critical scrutiny. First, social norms and psychological dispositions extending beyond the selfish motives of Homo economicus may have an important bearing on outcomes, even in competitive markets. Second, market outcomes depend on strat...
