Invertibility of graphs with a unique perfect matching
Sona Pavlikova, Daniel Sevcovic
In this paper we investigate invertibility of graphs with a unique perfect matching, i.e. graphs having a unique 1-factor. We recall the new notion of the so-called negatively inve…

Numerical and analytical methods for bond pricing in short rate convergence models of interest rates
Zuzana Buckova, Beata Stehlikova, Daniel Sevcovic
In this survey paper we discuss recent advances on short interest rate models which can be formulated in terms of a stochastic differential equation for the instantaneous interest…
