Long Heterochromatic Paths in Edge-Colored Graphs
Long Heterochromatic Paths in Edge-Colored Graphs
Let $G$ be an edge-colored graph. A heterochromatic path of $G$ is such a path in which no two edges have the same color. $d^c(v)$ denotes the color degree of a vertex $v$ of $G$. In a previous

Solving x^x = i
Date: 12/23/2000 at 01:04:03
From: Guy Pledger
Subject: Equation for x^x=i
This might be a nebulous question, but is there a way to find what
number raised to it's own power would yield i, that is, x^x = i? I
understand how imaginary exponents work and have done a lot with them,
but I see no way to solv... | {"url":"http://mathforum.org/library/drmath/view/52253.html","timestamp":"2014-04-20T01:16:55Z","content_type":null,"content_length":"6660","record_id":"<urn:uuid:6be0d769-7751-41e9-bf17-e570115025be>","cc-path":"CC-MAIN-2014-15/segments/1397609537804.4/warc/CC-MAIN-20140416005217-00180-ip-10-147-4-33.ec2.internal.warc... |
