 Oct20 comment Using Janet Basis to solve a nonlinear polynomial system May be this website could help you wwwb.math.rwth-aachen.de/Janet/index.html , the course is called computer algebra, but written in German, and it is unfortunately not available online. Sep14 comment Using Janet Basis to solve a nonlinear polynomial system I am looking to understand what is the relation between all these concepts, as answer to your question would like to say all solutions including complex solutions. Jun18 comment How many irreducible factors of grade $6$ there is in $\mathbb{F}_{2}\left[ x\right]$? Thanks, this is interesting, but still would like to know how could the hint above lead to solve the question. Apr27 comment Finding the smallest integer $n$ such that $1+1/2+1/3+…+1/n≥9$? Very nice, thanks a lot. Feb28 comment Fundamental group of the Klein bottle, using action of a group? this is very nice, thanks a lot. Oct19 comment G is a topological group acts on topological space $X$, is $f_{g}:X\rightarrow X, x\rightarrow g*x$ continuous? yes, actually $\phi:G\times X \rightarrow X$ is continuous, but how can we prove that $f_{g}:X\rightarrow X$ defined above is continuous May30 comment The relation between betti numbers and Tor functor? sorry, it is R. May29 comment computing betti numbers using Macaulay program ?? this is very nice, thanks for the quick answer Apr20 comment generators of alternating groups? yes there is a theorem says that $A_{n}=<(123),(234),(345),......((n-2)(n-1)n)>$ from this theorem we can say that $A_{4}=$ \\ it is clear $x=a$, and $z=a^{-1}b$, so one just need to know how y could be written in terms of a,b.
