Complementary Inequalities Involving the Stolarsky Mean

Let n be a positive integer and p, q, a, and b real numbers satisfying p > q > 0 and 0 < a < b. It is proved that for the real numbers a1, . . . , an ∈ a, b , the maximum of the function fp,q a1, . . . , an a p 1 · · · a p n /n − aq1 · · · a q n /n p/q is attained if and only if k n of the numbers a1, . . . , an are equal to a and the other n − k n are equal to b, while k n is one of the values...

Serendipitous insights involving nonhuman primates.

Serendipity is discussed as a form of controlled chaos, a phenomenon in a class with synchronicity and other actions affecting research in terms of theory versus observation (e.g., "optional stopping"). Serendipity is a fundamental aspect of basic research, a profitable and normal outcome in the context of "informed observation." The serendipitous finding fits into the following pattern: it is ...

Interactions involving D-branes

We investigate some aspects of the spectrum of D-branes and their interactions with closed strings. As argued earlier, a collection of many D-strings behaves, at large dilaton values, as a single multiply wound string. We use this result and T-duality transformations to show that a similar phenomenon occurs for effective strings produced by wrapping p-branes on a small (p-1)-dimensional torus, ...

Revealing AGN by Polarimetry

Polarimetric study in the UV and optical has been one of the keys to reveal the structure and nature of active galactic nuclei (AGN). Combined with the HST’s high spatial resolution, it has directly confirmed the predicted scattering geometry of ∼100 pc scale and accurately located the hidden nuclear position in some nearby active galaxies. Recently, we are using optical spectropolarimetry to r...
