Frob enius endomorphisms of linear spaces Alexander E. Guterman During the last century many efforts were devoted to classifying Frobenius endomorphisms of matrices, i.e., transformations preserving certain matrix invariants. The first result in this area was obtained by Frobenius in 1896, who characterized all bijective linear transformations on the space of complex matrices Mn (C) that preserve the determinant function. ... I am preparing a textbook and a computer course in my research area. ...

... A set of formulae has been developed to correct aperture photometry for CTE loss with dependencies on the X and Y positions, the background counts, the brightness of the star, and the time of the observation. The observations indicate that for very faint stars on a very faint background, the CTE loss from the top to the bottom of a chip has increased from about 3% shortly after the cool-down of WFPC2 (April 23, 1994) to roughly 40% in February 1999. ...
