Born on June 10, 1952 in Sarajevo, Yugoslavia. Graduated 1977 in theorethical
mathematics from the Faculty of Mathematics, University of Belgrade,
where obtained MA in 1981 and Ph.D. degree in 1984,
with the thesis *Theory of Simple and Multiple Antisymmetry
in E ^{2} and E^{2}\{O}*. Pursued
advanced scientific program in colored symmetry at the University of
Kishinev, USSR in 1985 and 1988; Fulbright Scholar, USA, 1992
(canceled by UN sanctions). The professor of geometry at the
University of Nish and the associate of the
Mathematical Institute,
Belgrade. The author of the monograph

As a mathematician, I am not only interested in geometry, group theory,
mathematical crystallography, the theory of symmetry, antisymmetry,
colored symmetry, combinatorial geometry and knot theory, but also
in the ** visual geometry**: the symmetry analysis of visual
arts and ornamental design. The (pre)history of ornamental art
and real-world pattern analysis with applications to anthropology,
the psychology of visual perception and the history of mathematics,
are my other favorite subjects. The most of such interests coincide
with the research program and activities of the
ISIS-Symmetry
(

The concept of visual geometry I presented in the three monographs,
in some of my papers, at the conferences of *ISIS-Symmetry*
(Budapest, Hungary, 1989; Hiroshima, Japan, 1992; Washington DC,
USA, 1995), and in the series of lectures at the University of Wisconsin
(Madison, Dept. Math.), Indiana University (Bloomington, Dept.
Anthropology), Technische Universität (Vienna, Austria, Dept. Geometry),
*Symmetry and Visual Perception* at Faculty of
Philosophy (Belgrade, Dept. Experimental Psychology),
*Symmetry and Visual Arts* at the National Museum (Belgrade),
and at the Museum of Contemporary Art (Belgrade).

Trying to materialize the symmetry approach to ornamental design,
I introduced *SpaceTiles*,
*KnotTiles*, and *OpTiles*
presented at the exhibitions: 2^ *Quadrienale
Internazionale: Ceramica nell arredo
urbano*, Faenza (Italy), 1989; *Symmetry of
Structure*, Interdisciplinary Symmetry Symposia 1,
National Gallery, Budapest (Hungary), 1989;
*XII European Crystallographic Meeting*, Moscow (USSR), 1989;
*International Industrial Design and
Technological Innovation Competition CEVISAMA*,
Valencia (Spain), 1987, 1994; *Symmetry: Natural and Artificial*,
Interdisciplinary Symmetry Symposia 3, Washington DC (USA), 1995.
One of them, *Two-Colored Ornamental
Tilings* earned an award at international design competition
*CEVISAMA'87* in Valencia (Spain). All of them, and some other
my works you could find as the Web presentations at at the
Mathematical Institute server (Yugoslavia),
as well at the Tripod server (USA).

If you are interested for the different aspects of visual mathematics: symmetry principles, knots, theory of mazes, knot projections (for which I developed a computer program), geometry of knots and links, Celtic art, ornamental design, key-patterns, Roman mazes and labyrinths, paleolithic ornaments, or op-art puzzles, please write me to the address: jablans@mi.sanu.ac.yu. Also, maybe we could share the joint hobbies: painting, wind-surfing, or collecting mushrooms.
