“…In recent years because of the development of the String Theory and Quantum Gravity (see, for example, [3,4]) the interest in the studies of noncommutativity has risen significantly. Different problems were studied in the framework of different types of noncommutativity, among them the harmonic oscillator [5][6][7][8][9][10][11][12][13], the hydrogen atom [10,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], the Landau problem [29][30][31][32], the gravitational quantum well [33,34], classical systems with various potentials [35][36][37][38][39][40], many-particle systems [10,14,[42][43][44][45][46], and many others.…”
