Title: Topics in Nonnegative Matrices

Syllabus/Outline: Review of eigenvalues and eigenvectors, Nonnegative Matrices, Graph associated with a matrix, Brouwer's Fixed Point Theorem, Perron's theorem for positive matrices, strongly connected graphs,irreducibility, Perron-Frobenius theorem for irreducible matrices, primitive, cyclic,reducible matrices (statements and examples), Inequalities for Perron root. Matrices over the max algebra.

Apoorva Khare
IISc

Title: Totally nonnegative (TN) and totally positive (TP) matrices

Syllabus/Outline: (a) Definitions, examples. (b) TP is dense in TN. (c) Eigenvalues of square TP/TN matrices are positive/nonnegative.

Parts (b) and (c) should remind one of the exact same statements for positive (semi)definite matrices -- the analogue of (c) is Sylvester's criterion. The proofs for TN/TP matrices will including my covering Perron's theorem for matrices with positive entries, Kronecker's theorem for compound matrices, and a black-box result on the continuity of the roots of complex polynomials as functions of the coefficients.

Title: Linear groups

Abstract: We introduce and study various groups of matrices. Orthogonal, Unitary and Symplectic groups are discussed and the exponential mapping on matrix groups will be studied. Various types of decompositions of these matrix groups will be described. Finally, symmetry groups of solids are analyzed.
