HGFei is editor in chief to JFAA (see here: local chief editors information on JFAA , including bibliographical information).  HGFei is president of the Mathematischer Zirkel (Statuten) at the Univ. of Vienna  and ALUMNI contact person for the department (cf. Alumni Home-Page der Uni Wien). JFAA homepage (Springer-Link), Editor-in-Chief's  local infos   

Publications

• HGFei's list of publications according to Zentralblatt as of (2002), or the current status (starts a search at Zentralblatt f. Math.). Alternatively there is a link to  MathSciNet  resp. pointing to papers authored by Hans G. Feichtinger .  An edited variant of this kind contains links to a selection of "older" papers  (from pre-TEX times) giving access to PDF or PS versions of older paper. Alternatively you may go directly to one of the following subdirectories:   http://www.univie.ac.at/NUHAG/FEI/finalps resp. http://www.univie.ac.at/NuHAG/FEI/finalps/PDF-PS/   (preliminary site, until the material is integrated into the NuHAG publications, showing then also the linked abstracts, explaining some of the connections, see in particular "earlier papers") or better via the following  WWW-page containing some comments. (this paragraph will be updated!)    
• NuHAG publications (NuHAG publication list), in particular you will find the books edited by HGFei there I have made some effort to move between the abstracts of my earlier and more recent papers in order to get some idea, how they are connected with each other. Thus it gives some information where the concepts introduced in the earlier papers turned out to be quite useful and relevant in my work in (Applied and Computational) Harmonic Analysis in recent years.
• Citeseer retrivial (citations of HGFei)
• For mathematicians the section "Selection of early papers" might be a good starting point for such a (hyper-text) tour.
  I have also compiled a "long list" of most of the abstracts into one long file (to be updated in 2003).
• My personal list of publications (Sept. 2002) as a PS-file  or alternatively in PDF format. .
• HGFei is associate editor ACHA, Journ. Approx. Theory, and the new  journals "Sampling Theory in Signal and Imaging Processing" STSIP and Function Spaces and Applications. 
• A short  self-characterization of NuHAG  (in German language, prepared Sept. 2002)
• Some statements about the (prae)history and output of NuHAG (around 2000)
• There is a number of pamphlets by HGFei , available, which you may read for your pleasure

• later on material concerning pamphlet will be found HERE!

• ...  applied abstract ( = conceptual!) harmonic analysis

• Gabor expansions and time-frequency localization

• irregular sampling or scattered data approximation, atomic decompositions 

• non-orthogonal expansions, Banach frames, Riesz projection bases  

• signals of variable band-width, time-variant filtering, Gabor multipliers 

• Banach spaces of distributions on locally compact (Abelian) groups

• generalized Fourier analysis, convolution, pseudo-differential operators

• wavelet theory and function spaces, in particular modulation spaces 

• MATLAB as a mathematical research and teaching tool

Private matters and interests

• Katharina Feichtinger- Ziniel  we live in Mistelbach
• Children (2nd generation):
  • Lena Elisa (Aug. 27th, 1996)
  • Lukas Fabian (Jun. 22nd, 1998) ( my favorite test image, as of June 2002)  

  Pictures of my family  (year 2000), and some  more recent ones here (also "outdated by now")

• Music: classical, ethnic = World Music, Jazz; Folk-Music (e.g. Irish), French Chansons, Percussive Music
• Sports: biking, skiing, skating, roller-skating, wind-surfing,
• Instruments: Piano ("private" improvisation), owning a YAHAMA CLP-970, African drums (but also drums from Turkey, India, etc.)
• International contacts, traveling
• Science politics (in particular interdisciplinary), contacts with engineers, medical researchers, musicians, etc.
• Convincing colleagues from applied sciences that pure mathematics can be both understandable and helpful
• Convincing colleagues from pure mathematics that applications can be mathematically beautiful and intellectually challenging
• bring people together, host visitors, enable students to work in an interdisciplinary way

• establish NuHAG as an international "long term, global player" within the European research landscape  

Miscellaneous

• A list of some of the visitors that have seen us in the late 90's or  more recently.
• Some informations concerning my advisor H.Reiter's book and a list of H.Reiter's PhD-students in Utrecht and Vienna.
• I am working on a (still incomplete) listing of conference participations, cf. NuHAG outgoing visits.
