Marvellous.
Thank you debasis
Kya ring homomorphism ideal ki help se nhi count kar sakte h
Like we count group homomorphism with the help of Normal subgroup
Thank you sir
Sir wt is the shortcut to get the elements of a particular order in Zn ...(how did u get 5 and 25 so quickly with order 6?)
plz watch the lecture in the topic cyclic group in the playlist, you will definitely get your answer
Thank u very much sir.. Doing very well...
Thank you
abbe kya doing very well ye to smjh ni aya ki F(a) = 5,25 kaha se aya??
@@dronakathuria6893 |f(a)|=6 then codomain matlab Z30 k woh elements jinka order 6 ho kyunki codomain Z30 m hi f(a) milty hai for all a
Sir you are great
here number of ring hommorphism is 0,1,6,15,21,25,26 these are all idempotent elment in Z30
f(1)=5 kyu liye?
just use the property of homomorphism
Could you please make video about z6 to z12?
very easy, first do group homomorphism
@@MathematicalScience which books do you use it is of especially du or only author name?
@@MathematicalScience I am not able to understand f:z50 to z15 and f(3)=6 and determine f(1) plz suggest
@@iqramanzoor7250 Gallian for any univ.
If we want to know ring homomorphism from Z20 to Z30, then is it the same procedure as this one ?
Yes
How 15²=15
Its modulo operation
jaise hi kaam ki baat aati hai tum skip kr dete ho bhai
Kya skip Kiya mohan ji?
Not well and details explain... Plz sur details explain karo
Okay, Thank you for suggestion
@@MathematicalScience sir don't angry plz ... Jab app 5 and 25 likha wahna sabka doubt hote honge bcz wo kaha se laya apne bataya hi nehi ...
@@niranjanbehera2082 5 and 25 are the element whose order is 6 in Z30, detailed video you can check advanced group theory playlist counting group homomorphism
