Anna Hofer
Ph.D. candidate in combinatorial and computational commutative algebra
My research lies at the intersection of combinatorics, commutative algebra, and computation, with a focus on developing algorithms and software for computations in commutative algebra.
● About
I am a Ph.D. student at Otto von Guericke University Magdeburg in Thomas Kahle's research group, funded by the DFG priority program Combinatorial Synergies. I obtained both my Bachelor's and Master's degrees at OvGU under the supervision of Thomas Kahle.
My research focuses on combinatorial and computational commutative algebra. In particular, I am interested in combinatorial structures that provide insight into algebraic objects, as well as in the development of algorithms and software for computations in commutative algebra.
Outside of maths, I love sport — especially running, cycling, swimming, and climbing. I also enjoy learning languages and reading.
● Software
Open-source contribution
Injective resolutions & local cohomology in OSCAR
I implemented the computation of injective resolutions and local cohomology over normal affine semigroup rings in OSCAR, the Julia-based computer algebra system. The functionality is now part of OSCAR. Joint work with Thomas Kahle.
