Some nonlinear differential inequalities and an application to Hölder continuous almost complex structures
Adam Coffman, Yifei Pan
We consider some second order quasilinear partial differential inequalities for real valued functions on the unit ball and find conditions under which there is a lower bound for th…

CR singularities of real fourfolds in
Adam Coffman
CR singularities of real 4-submanifolds in complex 3-space are classified by using local holomorphic coordinate changes to transform the quadratic coefficients of the real analytic…
