A new spectral invariant for quantum graphs

Autor: Michał Ławniczak, Pavel Kurasov, Szymon Bauch, Małgorzata Białous, Afshin Akhshani, Leszek Sirko

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-9 (2021)

Abstract The Euler characteristic i.e., the difference between the number of vertices |V| and edges |E| is the most important topological characteristic of a graph. However, to describe spectral properties of differential equations with mixed Dirichl

Isoscattering strings of concatenating graphs and networks

Autor: Michał Ławniczak, Adam Sawicki, Małgorzata Białous, Leszek Sirko

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-8 (2021)

Abstract We identify and investigate isoscattering strings of concatenating quantum graphs possessing n units and 2n infinite external leads. We give an insight into the principles of designing large graphs and networks for which the isoscattering pr

Experimental Investigation of the Generalized Euler Characteristic of the Networks Split at Edges

Autor: Omer Farooq, Afshin Akhshani, Małgorzata Białous, Szymon Bauch, Michał Ławniczak, Leszek Sirko

Publikováno v: Mathematics, Vol 10, Iss 20, p 3785 (2022)

We discuss a connection between the generalized Euler characteristic Eo(|VDo|) of the original graph which was split at edges into two separate subgraphs and their generalized Euler characteristics Ei(|VDi|), i=1,2, where |VDo| and |VDi| are the numb

Investigation of the generalized Euler characteristic of graphs and microwave networks split at edges and vertices

Autor: Omer Farooq, Afshin Akhshani, Małgorzata Białous, Szymon Bauch, Michał Ławniczak, Leszek Sirko

Publikováno v: Physica Scripta. 98:024005

We analyze the situation when the original graph is split at edges and vertices into two disconnected subgraphs. We show that there is a relationship between the generalized Euler characteristic  o ( ∣ V D o ∣ ) of the original graph and the g
