Continental and Sub-Continental Income Inequality
Continental and Sub-Continental Income Inequality Income inequality can be measured at different levels of aggregation such as global, continental, international and national levels. Here we consider income inequality at regions defined as equivalent of continental and sub-continental levels. We investigate the economic disparity between regions of the world and among countries within each cont...
متن کاملمطالعه نشاننده های cr-epic و فضاهای cr-epic مطلق
مطابق معمول حلقه توابع پیوسته حقیقی مقدار روی فضای تیخونوف x را با c(x) نمایش می دهیم. اگر برای هر نشاننده ی توپولوژیکf : x?y نگاشت القایی ?:c(y)?c(x) اپی مورفیس در کاتگوری حلقه های جابجایی باشد. آنگاه فضای xرا فضایی cr-epic مطلق می نامند.فضا های تقریبا فشرده و p-فضاهای لیندلوف از ساده ترین این نوع فضاها می باشند.

We present the results of a friendly competition for formal verification of continuous and hybrid systems with nonlinear continuous dynamics. The friendly competition took place as part of the workshop Applied Verification for Continuous and Hybrid Systems (ARCH) in 2017. This year, three tools CORA, Flow* and Isabelle/HOL (in alphabetic order) participated. They are applied to solve the reacha...

Although clausal propositional proofs are significantly smaller compared to resolution proofs, their size on disk is still too large for several applications. In this paper we present several methods to compress clausal proofs. These methods are based on a two phase approach. The first phase consists of a light-weight compression algorithm that can easily be added to satisfiability solvers that...

We describe our initial experiments with several state-of-the-art automated theorem provers on the problems in Tarskian Geometry created by Beeson and Wos. In comparison to the manually-guided OTTER proofs by Beeson and Wos, we can solve a large number of problems fully automatically, in particular thanks to the recent large-theory reasoning methods.
