Gt - please explain the following problem.(p 13,q 21)

Sir can you please mention the formula for finding " number of non isomorphic abelian groups?"

See the attachments for ur clarification

In the first board image, G is abelian group... I mistakenly haven't wrote it.

do you still have any doubt? ask me

ok sir.

Thank you sir, I understood. Sir can you please mention the names of some standard books from which we get direct Q or similar Q in CSIR NET Examination.

From my own experience, I will suggest you that CSIR is such an examination where you can't go with results. You must have to develop good conceptual knowledge in atleast two scoring papers. Otherwise, u will not be able to score in part C

Part C tests ur conceptual knowledge. Therefore, try to strengthen your two papers atleast. For linear algebra, I would suggest you schaum series as a beginner to get the knowledge of what's going on and then u can follow either friedberg or Hoffman's kunje

For real analysis, follow S k mapa initially. For modern algebra, follow Gallian.

Apart from this, solve previous year questions atleast once. This will give you exact idea of the pattern of CSIR questions

then try to solve as many questions do you get... but plz dedicate urself to gain actual depth conceptual knowledge in atleast 2 papers. This will help u in part C

Thank you sir ," 2 papers" in the sense 2 units ?

choose atleast one from the unit 1.... atleast real analysis or linear if you can....these are most scoring topics

Ok sir, thank you.
