Hebrew University Amitsur Algebra Seminar ---------------------------------- Time: Thursday, Nov 8 , 12:00-13:15 Place: math 209 Speaker: Alexander Guterman (Moscow State University) Title: On the Polya problem of conversion between permanents and determinants Abstract: (See also the pdf file of the abstract at: <http://www.math.technion.ac.il/~techm/temp/20121108GUTE.pdf> ) Two important functions in matrix theory, determinant and permanent, look very similar. While the computation of the determinant can be done in a polynomial time, it is still an open question, if there exists a polynomial algorithm to compute the permanent. Due to this reason, starting from the work by Polya, 1913, different approaches to convert the permanent into the determinant were under the intensive investigation. Among our results we prove the following theorem: Suppose n>=3, and let F be a finite field with char(F) not equal 2. Then, no bijective map T:M_n(F) ---> M_n(F) satisfies per( A) = det (T(A)).
