Algebraic distance between submodules
(Beograd : Académie Serbe des sciences et des arts, 2019)
We investigate the algebraic distance between closed and orthogonaly complemented submodules of a Hilbert C-module, which is defined as the norm of a difference
of corresponding orthogonal projections. Some results are ...
Asymptotically almost periodic and asymptotically almost automorphic solutions of abstract degenerate multi-term fractional differential inclusions with Riemann-Liouville derivatives

Graph energies and their applications
(Beograd : Académie Serbe des sciences et des arts, 2019)
The energy E(G) of a graph G is the sum of absolute values of the
eigenvalues of the adjacency matrix of G. This spectral quantity was introduced in 1978 by
Ivan Gutman, but its extensive research started only twenty ...
Special cases of orthogonal polynomials on the semicircle and applications in numerical analysis
(Beograd : Académie Serbe des sciences et des arts, 2019)
Orthogonal polynomials on the semicircle was introduced by Gautschi and
Milovanovic in ´ [Rend. Sem. Mat. Univ. Politec. Torino, Special Issue (July 1985), 179−185]
and [J. Approx. Theory 46 (1986), 230 − 250]. In this ...

Eminent scientist Aleksandar Sanja Ivić, Full Member of the Serbian Academy of Sciences and Arts (SANU), passed away on December 27, 2020, after a vicious illness he faced with an unprecedented will, but unfortunately he ...
Spectral theory of Smith graphs
(Beograd : Académie Serbe des sciences et des arts, 2017)
Graphs whose spectrum belongs to the interval [−2, 2] are called Smith
graphs. The structure of a Smith graph with a given spectrum depends on a system of Diofantine
linear algebraic equations. We establish several ...
Generalized Laplace transform of locally integrable functions defined on [0,∞)
(Beograd : Académie Serbe des sciences et des arts, 2017)
In [Bull. Cl. Sci. Math. Nat. Sci. Math. 40 (2015), 99 − 113] we defined
the Laplace transform on a bounded interval [0, b], denoted by 0L, using some ideas of H.
Komatsu [J. Fac. Sci. Univ. Tokyo, IA, 34 (1987), 805–820] ...
On hyper–Zagreb index and coindex
(Beograd : Académie Serbe des sciences et des arts, 2017)
Let G be a graph with vertex set V and edges set E. By d(v) is denoted
the degree of its vertex v. Two much studied degree–based graph invariants are the
first and second Zagreb indices.
A recently proposed new invariant ...
