## L. C. Wang's policy for his mathematical articles

###
The duty of mathematicians is to provide good ideas and the duty of
mathematical journals is to popularize the ideas to facilitate learning and
discourse. When a mathematician contributes to the mathematical community by
providing good ideas, he or she should not share the burden of a mathematical
journal's printing cost. L. C. Wang welcomes any academic journal to publish L.
C. Wang's articles. However, L. C. Wang does not accept publishing bills from
any mathematical journal. Any publishing bill received by L. C. Wang will be
discarded.
