In this paper, we discuss maximality of Seidel matrices with a fixed largest eigenvalue. We present a classification of maximal Seidel matrices of largest eigenvalue 3, which gives a classification of maximal equiangular lines in a Euclidean space wi

Ring-opening transformations of donor-acceptor (D-A) cyclopropanes enable the rapid assembly of complex molecules. However, the enantioselective formation of chiral quaternary stereocenters using substrates bearing two different acceptors remains a c

We give a survey on graphs with fixed smallest adjacency eigenvalue, especially on graphs with large minimal valency and also on graphs with good structures. Our survey mainly consists of the following two parts: At the end of the survey, we also dis

With the aid of a class of newly discovered Trost-type bisphosphine ligands bearing a chiral cycloalkane framework, the Pd-catalyzed decarboxylative dearomative asymmetric allylic alkylation (AAA) of benzofurans was achieved with high efficiency [0.2

Four newly designed CyPHOX ligands with chiral cyclohexane scaffold replacing the previous planar aryl group of PHOX ligands, were efficiently prepared. The synthesis features a kinetically controlled asymmetric phos-Michael reactions of trisubstitut
In this paper we give two characterizations of the $p \times q$-grid graphs as co-edge-regular graphs with four distinct eigenvalues.

In this paper we show that the conjecture of Lemmens and Seidel of 1973 for systems of equiangular lines with common angle arccos ( 1 / 5 ) is true. Our main tool is forbidden subgraphs for smallest Seidel eigenvalue −5.
