Beethoven Sonata no.30 op. 109

[precipitato]

Hi all

I am currently analyzing the work. For the 3rd movement, 5th variation, some people have said that it was a fugue, not others. This has made me rather confused...

Is it really a fugue...? It is indeed reminiscent of the Baroque structure.

Although I also use to call it a fugue, I think I'm wrong 

I see some kind of tribute to Bach in Vars III and V. I see Var III as some kind of two part invention and Var V a four part invention. Var V has has obviously counterpoint and imitations and it has a poliphonic repetitive form but I don't think it's (strictly speaking) a fugue
