**Recent theoretical developments in the integer quantum Hall effects*

The quantum Hall effects belong to the most striking phenomena in 
condensed matter physics. Despite of intensive theoretical efforts over 
the last three decades, important aspects of the quantum Hall 
transitions are still not fully understood. In particular, there is 
still no consensus concerning the critical field theory and the 
corresponding scaling properties of the observables near and at the 
plateau transition.
Notwithstanding this status, the last ten years have seen considerable 
progress in understanding basic properties of scaling near 
localization-delocalization transitions that have implications also for 
the quantum Hall transition. These concern, e.g., the important topic of 
corrections to scaling, the wavefunction statistics and higher-order 
multifractality. A brief review of these developments will be offered in 
the first part of the talk.
The second part of the talk will be devoted to the spin quantum Hall 
effect, which is a variant of the integer quantum Hall effect (class A) 
taking place in the Altland-Zirnbauer class C. For this transition 
several critical exponents are known analytically and can serve as 
reference points. Therefore, this transition provides an ideal testbed 
for the qualitative predictions made by analytical theories. Analytical 
predictions will be confronted with most recent numerical results.
