Synthetic geometry of differential equations: I. Jets and comonad structure | We give an abstract formulation of the formal theory partial differential
equations (PDEs) in synthetic differential geometry, one that would seamlessly
generalize the traditional theory to a range of enhanced contexts, such as

both. A mo... | 0 | 0 | 1 | 0 | 0 | 0 |
Precision Prediction for the Cosmological Density Distribution | The distribution of matter in the universe is, to first order, lognormal.
Improving this approximation requires characterization of the third moment

Hamiltonian analogs of combustion engines: a systematic exception to adiabatic decoupling | Workhorse theories throughout all of physics derive effective Hamiltonians to
describe slow time evolution, even though low-frequency modes are actually
coupled to high-frequency modes. Such effective Hamiltonians are accurate

Towards Arbitrary Noise Augmentation - Deep Learning for Sampling from Arbitrary Probability Distributions | Accurate noise modelling is important for training of deep learning

Integrating Runtime Values with Source Code to Facilitate Program Comprehension | An inherently abstract nature of source code makes programs difficult to
