The Constructive Second Number Class*
The existence of at least a vague distinction between what I shall call the constructive and the non-constructive ordinals of the second number class, that is, between the ordinals which can in some sense be effectively built up to step by step from below and those for which this cannot be done (although there may be existence proofs), is, I believe, somewhat generally recognized. My purpose he...

متن کاملGauge invariant formulation of systems with second class constraints.
Gauge invariant formulation of systems with second class constraints. The covariant quantization of physical systems with reducible constraints is one of the unresolved problems which appear in connection with the Green-Schwarz Superstring (GSSS).The formulation of the GSSS [1] presents several advantages over the perturbative NRS formulation [2]. In particular a non perturbative second quantiz...
متن کاملefl students gender and socioeconomic status: the use of politeness strategies in the first and second languages
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
On Shintani’s ray class invariant for totally real number fields
We introduce a ray class invariant X(C) for a totally real field, following Shintani’s work in the real quadratic case. We prove a factorization formula X(C) = X1(C) · · ·Xn(C) where each Xi(C) corresponds to a real place (Theorem 3.5). Although this factorization depends a priori on some choices (especially on a cone decomposition), we can show that it is actually independent of these choices ...
