$K$-Theorie adischer R\'aume

The present work is the author's doctoral thesis, written during his studies at the University of Bonn. Its goal is to establish the foundations of $K$-theory in the context of adic geometry using the formalism of condensed mathematics and Efimov's results on localizing invariants of dualizable categories. In particular, we study the descent properties of our version of $K$-theory and prove that it satisfies Nisnevich descent on analytic adic spaces. Furthermore, we show that $K$-theory forms a sheaf with respect to the \'etale topology after chromatic localization. Finally, we use this result to prove an analog of the Grothendieck-Riemann-Roch theorem for analytic adic spaces. ; Comment: in German
