معرفی
PD Dr. Jörg Koppitz is a researcher at the Institute of Mathematics at the University of Potsdam, where he maintains an active research program in discrete mathematics and algebra. His office is located at Campus Golm, Building 9 (Space: II.09.3.13) with contact information including phone (+49 331 977-1551) and email (koppitz@rz.uni-potsdam.de).
Dr. Koppitz's research focuses span three main areas: Discrete Mathematics (including essential variables in n-valued functions, arity gaps, and essential positions in trees); Semigroup theoretical problems (particularly order-preserving transformation semigroups, orientation-preserving transformation semigroups, and maximum subsemigroups); and Universal Algebra (covering hypersubstitutions, solid classes, clones of operations, and varieties of algebraic structures).
Analysis of his recent publications reveals a consistent trajectory in semigroup theory with increasing specialization in transformation semigroups and their algebraic properties. His work demonstrates strong international collaboration, particularly with researchers from Bulgaria, Thailand, and other European institutions. The publications show progression from foundational work on hypersubstitutions to more specialized investigations of transformation semigroups with various constraints.
As an educator, Dr. Koppitz taught courses in the summer semester of 2018 including Seminar on Conceptual Analysis (using Formal Concept Analysis: Mathematical Foundations by Ganter and Wille) and Mathematics II for Computer Science Students. His teaching approach emphasizes handwritten exercises and regular assessment through interim tests.
His research environment is centered at the University of Potsdam's Institute of Mathematics, which provides the infrastructure for his theoretical mathematical work. While specific laboratory facilities aren't mentioned (as would be expected in pure mathematics), his collaborative publications suggest active participation in the international mathematical research community through conferences and academic exchanges.
