Bir kristalde elektron dinamiği
Çelik, Derya (Anadolu Üniversitesi, 1992)Bir kristal, üç boyutlu uzayda periyodik olarak tekrarlanan bir desenin atomlarından meydana gelmiş bir katı olarak tarif edile- bilir. Periyodik cetvele bakıldığında katıların önemli bir kısmını metaller oluşturmaktadır. ... -
An equivalence class decomposition of finite metric spaces via Gromov products
Bilge, Ayşe Hümeyra; Çelik, Derya; Koçak, Şahin (Elsevier Science BV, 2017)Let (X, d) be a finite metric space with elements P-i, i = 1,..., n and with the distance functions d(ij) The Gromov Product of the "triangle" (P-i, P-j, P-k) with vertices P-t, P-j and P-k at the vertex Pi is defined by ... -
Fractal interpolation on the Sierpinski Gasket
Çelik, Derya; Koçak, Şahin; Özdemir, Yunus (Academic Press Inc Elsevier Science, 2008)We prove for the Sierpinski Gasket (SG) an analogue of the fractal interpolation theorem of Barnsley. Let V-0 = [p(1), p(2), p(3)) be the set of vertices of SG and u(i) (x) = 1/2 (x + p(i)) the three contractions of the ... -
A Fractal Representation of the Complex Clifford Algebra Equivalent to the Fock Representation
Çelik, Derya; Koçak, Şahin (Birkhauser Verlag Ag, 2012)We construct a representation of the infinite dimensional complex Clifford algebra on the Hilbert space of square-integrable complex-valued functions on the Cantor set, which we show to be equivalent to the classical Fock ... -
Graph-directed sprays and their tube volumes via functional equations
Çelik, Derya; Koçak, Şahin; Özdemir, Yunus; Üreyen, Adem Ersin (European Mathematical Soc, 2017)The notion of sprays introduced by Lapidus and his co-workers has proved useful in the context of fractal tube formulas. In the present note, we define a notion of a graph-directed spray, associated with a weighted directed ... -
Representations of Clifford Algebras on Function Spaces on the Cantor Set
Çelik, Derya; Koçak, Şahin; Özdemir, Yunus (Birkhauser Verlag Ag, 2011)We give a representation of the (infinite-dimensional) complex Clifford algebra on the Hilbert space of square-integrable complexvalued functions on the Cantor set.
