0 I'm making a platform which involves the server triggering Audio to be played with Socket.io. I'm trying to make a PWA for iOS using similar code, but it just doesn't work and I've heard that Safari requires user interaction (I am using this with the full screen PWA meta tag, not through Safari directly). It works fine on the latest version of Chrome on desktop. Is there anyway to make this work?

8 3 $begingroup$ My friend asks me how to compute the homology group of $X=SL(2,mathbb{R})/SL(2,mathbb{Z})$ . It is not hard to see that $H_0(X)=mathbb{Z}$ , and for $qge 4$ we have $H_q(X)=0$ . But I don't know how to compute $H_q(X)$ for $q=1,2,3$ , since the action of $SL(2,mathbb{Z})$ seems 'strange' to me, and I can't make $X$ into a CW complex. Can anyone help me? algebraic-topology manifolds homology-cohomology share | cite | improve this question edited Jan 16 at 7:36 Bonbon asked Jan 16 at 5:52
