nternational Press of Boston, Inc. is an academic publishing company founded in 1992. After eighteen years of growth, International Press now publishes fifteen journals in various fields of academic mathematics research, including a prestigious journal of statistics. International Press also publishes high-level mathematics and mathematical physics book titles, including monographs, textbooks, and more.International Press enjoys a productive partnership with the American Mathematical Society, with whom we have co-published the AMS/IP Studies in Advanced Mathematics book series since 1997.Having close ties to the Chinese mathematics community, International Press has also developed a close partnership with Higher Education Press of Beijing—the leading Chinese curriculum planner, and publisher and distributor of academic books—as well as with the Chinese publishers Tsinghua University Press, Hunan Science and Technology Press, and others.

Topology and its Applications is primarily concerned with publishing original research papers of moderate length. However, a limited number of carefully selected survey or expository papers are also included. The mathematical focus of the journal is that suggested by the title: Research in Topology. It is felt that it is inadvisable to attempt a definitive description of topology as understood for this journal. Certainly the subject includes the algebraic, general, geometric, and set-theoretic facets of topology as well as areas of interactions between topology and other mathematical disciplines, e.g. topological algebra, topological dynamics, functional analysis, category theory. Since the roles of various aspects of topology continue to change, the non-specific delineation of topics serves to reflect the current state of research in topology.At regular intervals, the journal publishes a section entitled Open Problems in Topology, edited by J. van Mill and G.M. Reed. This is a status report on the 1100 problems listed in the book of the same name published by North-Holland in 1990, edited by van Mill and Reed.Benefits to authorsWe also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.
