(1) Among his many mathematical achievements can be included profound discoveries in logic, algebra and differential equations.

(2) He had a distinguished career as a math professor, specializing in algebra , algebraic geometry and number theory.

(3) Courses in algebra, geometry, and Newtonian physics

(4) He failed in his application for the chair of algebra and number theory at Uppsala University.

(5) We have looked briefly at Zorn's contributions to algebra and to set theory.

(6) He wrote several books on arithmetic, algebra , geometry and astronomy.

(7) Ernst Schru00d4u00f6u00a3u251cu00e9der's important work is in the area of algebra , set theory and logic.

(8) It was an exciting time with increasing mathematical activity in algebra .

(9) Wall's research is mostly in the area of geometric topology and related algebra .

(10) Mill only deals with geometry, arithmetic, and some algebra , not the branches of higher mathematics.

(11) It is devoted mainly to arithmetic and algebra , with just a few problems on geometry and mensuration.

(12) The book contained the elements of geometry and algebra in addition to the calculus.

(13) He worked on algebra and graph theory, combining the two to produce his first outstanding contribution to matroid theory.

(14) Aitken's mathematical work was in statistics, numerical analysis, and algebra .

(15) Algebra problem

(16) I do not doubt that this is the most important work on general algebra that the Annalen has ever published.

(17) It is time to take a look at this most outstanding work on algebra in Greek mathematics.

(18) Ku00d4u00f6u00a3u251cu00e9nig worked on a wide range of topics in algebra , number theory, geometry, set theory, and analysis.

(19) They are the basis of mathematical logic, which in turn gives rise to Boolean algebra .

(20) In short, his interest in classical algebra and number theory brought him to abstract semigroups.
