Field Energy in Classical Gravity

The problem of negative total energy of certain mass systems in classical gravity and its connection with the existence of space-time singularities is brie y summarized. Some attempts to solve this problem are discussed, pointing out especially the possibility that rest masses of a gravitating systems could depend on the strength of the gravitational eld. The results are confronted with some ex...

Uniformly classical quasi-primary submodules

In this paper we introduce the notions of uniformly quasi-primary ideals and uniformly classical quasi-primary submodules that generalize the concepts of uniformly primary ideals and uniformly classical primary submodules; respectively. Several characterizations of classical quasi-primary and uniformly classical quasi-primary submodules are given. Then we investigate for a ring $R$, when any fi...

Detection of Gravitational waves with semi classical features and cosmological implications (of such semi classical features)

We argue in this document that initial vacuum state values possibly responsible for GW generation in relic conditions in the initial onset of inflation may have a temporary unsqueezed , possibly even coherent initial value, which would permit in certain models classical coherent initial gravitational wave states Furthermore, several arguments pro and con as to if or not initial relic GW should ...

Classical quasi-primary submodules

In this paper we introduce the notion of classical quasi-primary submodules that generalizes the concept of classical primary submodules. Then, we investigate decomposition and minimal decomposition into classical quasi-primary submodules. In particular, existence and uniqueness of classical quasi-primary decompositions in finitely generated modules over Noetherian rings are proved. More...
