Celebratio Mathematica

Yvonne Cho­quet-Bruhat is one of the out­stand­ing math­em­aticians of this last cen­tury. She pi­on­eered the mod­ern math­em­at­ic­al study of Ein­stein’s the­ory of grav­it­a­tion — gen­er­al re­lativ­ity — and since the early 1950s has made fun­da­ment­al con­tri­bu­tions in a wide vari­ety of areas in math­em­at­ic­al re­lativ­ity. In ad­di­tion to this work, Yvonne Cho­quet-Bruhat has done out­stand­ing work in many areas in geo­met­ric ana­lys­is, dif­fer­en­tial geo­metry and the ana­lys­is of par­tial dif­fer­en­tial equa­tions. Last but not least, Yvonne has provided an ex­cep­tion­al role mod­el for fe­male math­em­aticians. We are very proud to present these es­says from ad­mir­ing friends in hon­or of Yvonne’s up­com­ing 100th birth­day in Decem­ber, 2023.
