In well-structured data, each variable (field) is in its own column, and each different observation of that variable (value) is in a different row. Variables can be discrete or continuous. Discrete variables have values that are separate and distinct, whereas continuous vari...
Various numerical methods have been developed in the last decades to solve reaction-diffusion equations. Many of those schemes belong to the classes of traveling wave method [46], finite element method [16], fixed-node finite-difference schemes [44], and spectral methods [8]. For instance, Re...
In certain established approaches to quantum gravity, such as causal set theory and causal dynamical triangulations, discrete spacetime structure is taken to be a primary feature, not a secondary effect of “quantizing” a pre-existing classical continuu
Into this tableau fits the relativity of identity as a postmodern "digital" addendum, arising from the information-theoretic properties of discrete causal spacetime models: 6. Relativity of identity: The observed identities of the components of a physical system in discrete causal theory, including ...
