Service of Proofreading

In order for the papers published in Progress of Theoretical Physics to receive their due recognition by the international physics community, we feel it necessary to maintain a high standard of English.   With this aim, it has been our policy for the papers appearing in Progress to undergo careful proofreading.

Proofreading fee: 1,000 yen/printed page
(we request the author to pay a part of the proofreading cost).
(In the case that payment is made from within Japan, the appropriate consumption tax is added.)
