Having defined the integers, we can now complete our initial remarks about the axiom of foundation, by saying that there are no decreasing ω-sequences u with ui+1 ω ui for each integer i. In particular for every integer r there is no cycle u1 ∈ u2 ∈…∈ ur ∈ u1. ...

Theorem 4 Let [G.sup.c] be a c-edge-colored graph with no PEC closed trails, s, t [member of] V([G.sup.c]) and a non- empty subset [PSI] of V ([G.sup.c]) \{s, t}. On paths, trails and closed trails in edge-colored graphs Let <R [union] I> be any neutrosophic ...
Introduction In data analysis with R, subsetting data frames based on multiple conditions is a common task. It allows us to extract specific subsets of data that meet certain criteria. In this blog post, we will explore how to subset a data fram...
Let's start with the easiest subsetting type of data structure in R that are Atomic Vectors. We will examine it by using a simple example of numeric vector. # Subsetting x <- c(1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7, 8.8, 9.9, 10.1) ...
