Kellog, OD (English spelling) KellogOD

…The solution to (4) is a fixed point of the operator that maps a continuous function to a continuous function x ( t ). Using this idea, GD Birkhoff and OD Kellogg (1878-1932) proved the existence of solutions to differential equations as a fixed point theorem for (not necessarily linear) completely continuous operators in Banach spaces. This idea was extended by JP Schauder (1899-1943), J. Leray (1906- ) and others to prove the existence of solutions to partial differential equations. …

…(4)の解は連続関数x(t)に連続関数を対応させる作用素の不動点である。この考えによりG.D.バーコフとケロッグO.D.Kellog(1878‐1932)は,微分方程式の解の存在を,バナッハ空間における(必ずしも線形でない)完全連続作用素の不動点定理として証明した。このような考え方は,シャウダーJ.P.Schauder(1899‐1943),ルレーJ.Leray(1906‐ )らによって,偏微分方程式の解の存在証明にも拡張された。…
