The integrability problem for 𝐺-structures [PDF]
Transactions of the American Mathematical Society, 1965 Introduction. One of the main problems of local differential geometry is to determine when a given differentiable structure (for example, a Riemannian structure, a projective structure or an almost complex structure) is integrable. There are really two problems involved in this: (1) the problem of finding a consistent system of differential equations ...

Time-lapse crystallography snapshots of a double-strand break repair polymerase in action
Nature Communications, 2017 DNA polymerase (pol) μ functions in DNA double-strand break repair. Here the authors use time-lapse X-ray crystallography to capture the states of pol µ during the conversion from pre-catalytic to product complex and observe a third transiently bound ...

On integrability of Golden Riemannian structures
Turkish Journal of Mathematics, 2013 The main purpose of the present paper is to study the geometry of Riemannian manifolds endowed with Golden structures. We discuss the problem of integrability for Golden Riemannian structures by using a f-operator which is applied to pure tensor fields.
