2017-03-06 19:27:37 +0200 | asked a question | Symmetry-finding On pp. 152-3 of Hydon's Symmetry Methods for Differential Equations (2000 ed.), he lists some computer packages for symmetry-finding. This related Mathematica StackExchange question mentions the SYM Mathematica package and Maple's DEtools/symgen. Does SAGE have anything similar for doing symmetry-finding? |

2015-03-18 07:07:19 +0200 | commented answer | implementing Lie-admissible algebras This is what I expected for an answer. I'm not looking for how to do every detail of such an implementation, but where to start. Thus, you've answered my question. thank you |
2015-03-17 19:38:39 +0200 | asked a question | implementing Lie-admissible algebras How would I implement Lie-admissible algebras in Sage? A Lie-admissible algebra is "A (non-associative) algebra (cf. Non-associative rings and algebras) whose commutator algebra becomes a Lie algebra." Read more. Lie-admissible algebras are classified as 17D25 on MSC2010. |

2015-03-17 07:13:22 +0200 | asked a question | performing a higher resolution FFT How do I interpolate (up-sample) a discrete function so that I can perform a more refined FFT spectral analysis on it? (Note: By default, NumPy's FFT command produces a list of the same dimension as the input list.) thanks |
