Mean convergence theorems with respect to attractive points in a Hilbert space
Koji Aoyama, Masashi Toyoda
In this paper, we show a mean convergence theorem for a mapping with an attractive point in a Hilbert space by using a quasinonexpansive extension of the mapping and a mean converg…
A quasinonexpansive extension of a mapping with an attractive point in a Hilbert space
Koji Aoyama
In this paper, we show that, under appropriate conditions, there exists a quasinonexpansive extension of a mapping with an attractive point in the sense of Takahashi and Takeuchi (…
Non-SUSY Heterotic String Vacua of Gepner Models with Vanishing Cosmological Constant
Koji Aoyama, Yuji Sugawara
We study a natural generalization of that given in [arXiv:2005.13198 [hep-th]] to heterotic string. Namely, starting from the generic Gepner models for Calabi-Yau 3-folds, we const…
Non-SUSY Gepner Models with Vanishing Cosmological Constant
Koji Aoyama, Yuji Sugawara
In this article we discuss a construction of non-SUSY type II string vacua with the vanishing cosmological constant at the one loop level based on the generic Gepner models for Cal…
