Work­ing field:

Work­ing in the Emmy Noe­ther rese­arch group „New Cer­ti­fic­ates of Non­neg­at­iv­ity and Their App­lic­a­tions in Sci­ence and Engin­eer­ing".
Decid­ing non­neg­at­iv­ity is a key prob­lem in real algeb­raic geo­metry with count­less app­lic­a­tions. The goal of the pro­ject is the invest­ig­a­tion and fur­ther devel­op­ment of non­neg­at­iv­itiy cer­ti­fic­ates based on sums of non­neg­at­ive cir­cuit poly­no­mi­als (SONCs). Next to the­or­et­ical ques­tions (e.g. struc­ture of the SONC cone, Pos­it­ivs­tel­len­sätze, max­imal medi­ated sets, rela­tion to amoe­bas) poten­tial app­lic­a­tions will also be invest­ig­ated, for example via exper­i­men­tal com­par­ison with cer­ti­fic­ates based on semi­def­in­ite pro­gram­ming. PhD the­sis pre­par­a­tion is pos­sible.


  • Suc­cess­fully com­pleted uni­versity degree (Mas­ter, Dip­lom or equi­val­ent) in Math­em­at­ics (or sim­ilar); excel­lent grades desired
  • Know­ledge in at least one of the fol­low­ing sub­jects: real algeb­raic geo­metry, con­vex optim­iz­a­tion (e.g. SDP), imple­ment­a­tion of math­em­at­ical soft­ware, dis­crete geo­metry.
  • Know­ledge of the fol­low­ing sub­jects is a plus: SONCs, amoe­bas, geo­met­ric / rel­at­ive entropy pro­gram­ming, advanced pro­gram­ming skills.
Ger­man lan­guage skills are not required. Fur­ther inform­a­tion on this pos­i­tion can be obtained from Dr. Timo de Wolff (
