Die Funktionentheorie der Differentialgleichungen $\mathrm{\Delta \; u\; =\; 0}$ und $\mathrm{\Delta \Delta \; u\; =\; 0}$

Fueter’s Die Funktionentheorie der Differentialgleichungen Δ u = 0 und ΔΔ u = 0 (1935) is part of the program’s reference corpus as standard domain context for Topology and Geometry. It is not directly cited in the currently published volumes of Panta Rhei, but is retained as part of the research shelf.
