Nonexistence of k-bounded sobrification
Jing Lu, Kaiyun Wang, Guohua Wu +1
In this paper, we will focus on k-bounded sober spaces and show the existence of a T_0 space X not admitting any k-bounded sobrification. This strengthens a result of Zhao, Lu and…
members of thin classes and generic degrees
Frank Stephan, Guohua Wu, Bowen Yuan
A class is thin if every subclass of is the intersection of with some clopen set. In 1993, Cenzer, Downey, Jockusch and Shore initiated the…
Existence of well-filterifications of topological spaces
Guohua Wu, Xiaoyong Xi, Xiaoquan Xu +1
We prove that for every space , there is a well-filtered space and a continuous mapping $η_X: X\lra W(X)$ such that for any well-filtered space and any continuo…
On Termination of Polynomial Programs with Equality Conditions
Yangjia Li, Naijun Zhan, Mingshuai Chen +3
We investigate the termination problem of a family of multi-path polynomial programs (MPPs), in which all assignments to program variables are polynomials, and test conditions of l…
Anti-complex sets and reducibilities with tiny use
Johanna N. Y. Franklin, Noam Greenberg, Frank Stephan +1
In contrast with the notion of complexity, a set is called anti-complex if the Kolmogorov complexity of the initial segments of chosen by a recursive function is always bou…
