Dear Colleagues,

Wavelet transforms serve as an important and powerful computational tool for describing complex systems and analyzing empirical continuous data obtained from many kinds of signals at different scales of resolution. They have been successfullyapplied for a wide range of problems arising in physics, mathematics, and engineering, especially in signal processing, image processing, sampling theory, differential and integral equations, function spaces, quantum mechanics, neurosciences, astrophysics, computer sciences, neural networks, nanotechnology, and medicine. Over the last couple of decades, there had been a continuous research effort in the study of wavelet transforms to develop new mathematical transforms, based on wavelets, including ridgelets, curvelets, contourlets, surfacelets, flaglets, beamlets, platelets, and shearlets. In addition to these, there has been a considerable interest in the problem of constructing wavelet bases on various spaces other than R, such as abstract Hilbert spaces, locally compact Abelian groups, p-adic fields, Hyrer-groups, Lie groups, and manifolds.

The main purpose of this Special Issue is to provide a multidisciplinary forum for contributions on these new ways of constructing wavelets and the most recent advances in its applications to real world problems. This Special Issue will also be an opportunity for extending the research fields of differential and integral equations, harmonic analysis, signal and image processing, approximation theory and practical studies of Physics and Engineering. This Special Issue is expected to welcome articles of significant and original results and survey articles of exceptional merit, which are closely related to wavelet transforms in either theoretical or applicative sense.

Potential topics include, but are not limited to:

• Continuous wavelet transforms
• Discrete wavelet transforms
• Fractional wavelet transforms
• Uncertainty principles
• Wavelet frames
• Contineous frames
• Shearlets
• Wavelets on manifolds
• Wavelets on p-adic fields
• Wavelets on Lie groups
• Applications

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Mathematics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
