Invariant theory has a long history, almost one-and-a-half centuries, and arose from certain problems from number theory, algebra, and geometry in the works of Gauss, Jacobi, Eisenstein, and Hermite. Invariants came into existence as a tool to distinguish and classify nonequival…

In this work we show that almost all useful ordinal invariants in topology studied until now (such as derived length of scattered spaces, sequential order of sequential spaces, etc.) can be brought under the single heading of what we call the order of a map. This helps us to per…
The main object of this memoir is to describe and, in some cases, to establish, new systems of congruences for the algebraic parts of the leading terms of the expansions of [italic]L-series at [italic lowercase]s = 0. If these congruences hold, together with a conjecture of Star…
