Totally Contact Umbilical Lightlike Hypersurfaces of Indefinite -Manifolds

Journal of Mathematics, 2013
We study totally contact umbilical lightlike hypersurfaces of indefinite -manifolds and prove the nonexistence of totally contact umbilical lightlike hypersurface in indefinite -space form.

Curvature of a class of indefinite globally framed $f$-manifolds

, 2008
We present a compared analysis of some properties of indefinite almost $\mathcal{S}$-manifolds and indefinite $\mathcal{S}$-manifolds. We give some characterizations in terms of the Levi-Civita connection and of the characteristic vector fields. We study

Remarks on some new models of interacting quantum fields with indefinite metric

, 1997
We study quantum field models in indefinite metric. We introduce the modified Wightman axioms of Morchio and Strocchi as a general framework of indefinite metric quantum field theory (QFT) and present concrete interacting relativistic models obtained by ...

Giving Up

Journal of Applied Philosophy, EarlyView.
ABSTRACT Philosophical accounts of long‐term goals focus predominantly on the rationality of perseverance, examining when agents should persist despite evidence of failure. Arguably, these accounts consider that giving up is devoid of value. Conversely, this article argues that giving up has a different epistemic function: generating information about ...

Integrations on rings

Open Mathematics, 2017
In calculus, an indefinite integral of a function f is a differentiable function F whose derivative is equal to f. The main goal of the paper is to generalize this notion of the indefinite integral from the ring of real functions to any ring.

Non-real eigenvalues of nonlocal indefinite Sturm–Liouville problems

Boundary Value Problems, 2019
The present paper deals with non-real eigenvalues of regular nonlocal indefinite Sturm–Liouville problems. The existence of non-real eigenvalues of indefinite Sturm–Liouville differential equation with nonlocal potential K ( x , t ) $K(x,t)$ associated ...

The Indefinite Logarithm, Logarithmic Units, and the Nature of Entropy [PDF]

, 2005
We define the indefinite logarithm [log x] of a real number x>0 to be a mathematical object representing the abstract concept of the logarithm of x with an indeterminate base (i.e., not specifically e, 10, 2, or any fixed number).

The Classical Moment Problem and Generalized Indefinite Strings

, 2017
We show that the classical Hamburger moment problem can be included in the spectral theory of generalized indefinite strings. Namely, we introduce the class of Krein-Langer strings and show that there is a bijective correspondence between moment ...
