I wondered about this one: sage: k=GF(2) sage: kx.<x>=GF(2)[] sage: kxy.<y>=kx[] sage: kx.extension(y^3+y+1) Univariate Quotient Polynomial Ring in y over Univariate Polynomial Ring in x over Finite Field of size 2 (using NTL) with modulus y^3 + y + 1 sage: exit Exiting Sage (CPU time 0m0.11s, Wall time 0m21.50s). Exiting Singular with PID 19781 running /usr/local/sage/sage-git/local/bin/Singular -t --ticks-per-sec 1000 --cntrlc=a
Observations: - this extension does not need a name specified, whereas in another case a name is required: sage: kx.<x>=GF(2)[] sage: k.extension(x^3+x+1) ValueError: parameter 'conway' is required if no name given - Polynomial quotient rings seem to trigger starting a separate Singular process. Shouldn't we be doing this with LibSingular? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
