Regina Tyshkevich


Regina Iosifovna Tyshkevich was a Belarusian mathematician, a professor of the Belarusian State University, and an expert in graph theory.
Her main scientific interests included Intersection graphs, degree sequences, and the reconstruction conjecture. She was also known for co-inventing split graphs and for her contributions to line graphs of hypergraphs.
In 1998, she was awarded the Belarus State Prize for her book Lectures in Graph Theory. Her textbook An Introduction into Mathematics written together with her two colleagues, presents mathematics as an integrated discipline, rather than a loose collection of problem-solving techniques.
In 2009, she was awarded the Francisco Scorina Medal.
An international conference "Discrete Mathematics, Algebra, and their Applications", sponsored by the Central European Initiative, was held in Minsk, Belarus, October 2009 in honor of her 80th birthday.
Regina Tyshkevich was a direct descendant of the Tyszkiewicz
magnate family, therefore her colleagues sometimes called her "the countess of graph theory", which is a pun in the Russian language: the Russian word "граф" is a homonym for two words meaning "count" and "graph".
