Frob enius endomorphisms of linear spaces Alexander E. Guterman My research interests are in ring theory, linear algebra and combinatorics. In particular, I investigate transformations on matrices over different algebraic structures, preserving some matrix properties, sets or invariants. ... I was investigating monotone matrix transformations and developed method of matrix deformations and chain method in order to classify monotone linear and additive transformations on matrices. ...

... 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. ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...
