DESCRIPTION:<span>Quillen proved that algebraic K-theory is A^1-invariant 
 on regular noetherian schemes. Vorst&rsquo\;s conjecture is a partial conv
 erse. Let k be a field\, and let A be a k-algebra essentially of finite ty
 pe and of dimension d. Vorst&rsquo\;s conjecture predicts that if K_{d+1}(
 A) = K_{d+1}(A[t_1\, \\dots\, t_m]) for all positive integers m\, then A i
 s regular. This conjecture was proven by Cortinas\, Haesemeyer\, and Weibe
 l in case k has characteristic 0. In the talk\, I will explain the proof o
 f a slightly weaker version of the conjecture if k has positive characteri
 stic. Joint work with Moritz Kerz and Florian Strunk.<br> <br> </span><br>
