arxiv_dataset-978812.1674 | Monadic approach to Galois descent and cohomology
math.CT
We describe a simplified categorical approach to Galois descent theory. It is
well known that Galois descent is a special case of Grothendieck descent, and
that under mild additional conditions the category of Grothendieck descent data
coincides with the Eil... | arxiv topic:math.CT |

We present UBVI photometry of the old open cluster NGC 1193. Color-magnitude
diagrams (CMDs) of this cluster show a well defined main sequence and a sparse
red giant branch. For the inner region of r<50 arcsec, three blue straggler
candidates are newly f... | arxiv topic:astro-ph |

We study the robustness and stability of the yeast cell regulatory network by

The parameters of a nondegenerate quantum code must obey the Hamming bound.
An important open problem in quantum coding theory is whether or not the
