Abstract: Results on the determination of the interval within which the coefficients of a globally positive multivariate polynomial might fluctuate without altering the positivity property are given.

Output data from modern Earth system model simulations are consuming increasingly massive amounts of storage resources, and storing these climate model data is not economically sustainable. Previous ...
