I propose to improve @FrédéricC's solution as below to avoid errors in certain cases : tuplesL=[ ((1,5,8,4),(2,6,7,3)

Thank you @Max Alekseyev

Ok @Max Alekseyev

@Max Alekseyev What do you mean ?

apply Permutation to a letters list Hi Sorry for this very basic question, but how to apply the Permutation function to

But that doesn't accept singletons is a minor problem

Hi

Sorry for this very basic question, but how to apply the Permutation function to a list of letters ? I think it should exist a simplest way than the the cooking below. I searched the web, without success !

def applyGen(ge,dic) :   
    return [ge[dic.get(e)] for e in dic.keys() ]

def decrement_dic(dic): 
    return {k - 1: v - 1 for k, v in dic.items()} 

lettersL=['a','b','c','d','e','f','g','h']

test=Permutation((1,5,8,4),(2,6,7,3))
dicD=decrement_dic(test.dict())
applyGen(lettersL,dicD)

ok thank you @FrédéricC

Hi W11,WSL,UBUNTU 22.04 ,SAGEMATH 10.2

test if zero of complicated algebra value gives infinite loop (if second t value uncommented)

t=-1/6*(1/4)^(1/3)*(3*sqrt(35)*sqrt(3) + 31)^(1/3)*(I*sqrt(3) + 1) - 2/3*(1/4)^(2/3)*(-I*sqrt(3) + 1)/(3*sqrt(35)*sqrt(3) + 31)^(1/3) + 1/3

#t= -1/12*sqrt((36*(1/24*I*sqrt(827)*sqrt(6) + 593/216)^(2/3) + 21*(1/24*I*sqrt(827)*sqrt(6) + 593/216)^(1/3) + 91)/(1/24*I*sqrt(827)*sqrt(6) + 593/216)^(1/3)) - 1/2*sqrt(-(1/24*I*sqrt(827)*sqrt(6) + 593/216)^(1/3) - 91/36/(1/24*I*sqrt(827)*sqrt(6) + 593/216)^(1/3) - 27/2/sqrt((36*(1/24*I*sqrt(827)*sqrt(6) + 593/216)^(2/3) + 21*(1/24*I*sqrt(827)*sqrt(6) + 593/216)^(1/3) + 91)/(1/24*I*sqrt(827)*sqrt(6) + 593/216)^(1/3)) + 7/6) - 1/4

show(t)
if t == 0 :
    print('zero')

@Max Alekseyev no it does not work too, because for you it is ok ? if yes, then, this problem is only due to my config

Is this reproducible for someone else or is it a problem with me?

complicated algebra test: infinite loop Hi W11,WSL,UBUNTU 22.04 ,SAGEMATH 10.2 test if zero of complicated algebra valu

Thank you @Max Alekseyev .

how do I get SageMath to give me both solutions?

# R.<theta_0,theta_1>=QQ[]
thetaVars=var('theta_0','theta_1')
aVars=var(['a_00', 'a_01', 'a_10', 'a_11'])
eqL=[]
eqL.append(3*theta_0^2 + 9*theta_0*theta_1 + 5*theta_1^2 == \
           a_00*theta_0^2 + a_01*theta_0*theta_1 + a_10*theta_0*theta_1 + a_11*theta_1^2)
eqL.append(-a_01*a_10 + a_00*a_11 == 1)

for eq in eqL :
    show(eq)
#how do I get SageMath to give me both solutions?    
# 2 solutions 
#s0=a_00==3,a_01==7,a_10==2,a_11==5
#s1=a_00==3,a_01==2,a_10==7,a_11==5

human can solve this 2 equations very easily for aVars

human can solve this equation very easily for aVars

W11,WSL UBUNTU SAGEMATH 10.2 solve(eqL,aVars) gives me something complicated, extract below: [[a_00 == -1/2*((r1 + r2

W11,WSL UBUNTU SAGEMATH 10.2 gives me something complicated extract below: [[a_00 == -1/2*((r1 + r2 - 9)*theta_0*theta

multivars eq ? how do I get SageMath to give me both solutions? # R.<theta_0,theta_1>=QQ[] thetaVars=var('theta_0

Hi look here maybe it could help you ?

Hi In my shortcut JupyterLab, I see this path : C:\Users\User\AppData\Local\Microsoft\WindowsApps\ubuntu2204.exe run ~/
