Biophysicists at JILA have measured protein folding in more detail than ever before, revealing behavior that is surprisingly more complex than previously known. The results suggest that, until now, mu...

In discussions of the possible connections between Copernicus and his Islamic predecessors, the so-called Ṭūsī-couple, invented by the 13th-century Persian polymath Naṣīr al-Dīn al-Ṭ...

2012/6/14
We introduce a new class of autoequivalences that act on the derived categories of certain vector bundles over Grassmannians. These autoequivalences arise from Grassmannian flops: they generalize Seid...

We prove that if $A$ is a regular graded skew Clifford algebra and is a twist of a regular graded Clifford algebra $B$ by an automorphism, then the subalgebra of $A$ generated by a certain normalizing...

In this paper we prove a relation between the period of an elliptic curve and the period of its real and imaginary quadratic twists. This relation is often misstated in the literature.

The Drinfeld twists or factorizing F-matrices for the open XXZ spin chain with non-diagonal boundary terms are constructed. It is shown that in the F-basis the two sets of pseudo-particle creation op...

On the Ranks of the 2-Selmer Groups of Twists of a Given Elliptic Curve.
Researchers in the US and Germany have developed a new way to transform DNA into complex shapes by making the molecules twist and bend. The technique could be crucial for making nanoscale device build...
