Morse functions constructed by random walks

Boldizsar Kalmar

We construct random Morse functions on surfaces by random walk and compute related distributions. We study the space of Morse functions through these random variables. We consider…

Some approximate solutions to the spread of influenza A virus infection

Boldizsar Kalmar

We study differential equations describing the spread of influenza A virus infection based on a mathematical model. We look for surface trajectories of the dynamical system in hand…

Concordance of decompositions given by defining sequences

Boldizsar Kalmar

We study the concordance and bordism of decompositions associated with defining sequences and we relate them to some invariants of toroidal decompositions and to the cobordism of h…

Decomposition space theory

Boldizsar Kalmar

In these notes we give a brief introduction to decomposition theory and we summarize some classical and well-known results. The main question is that if a partitioning of a topolog…

Fold cobordisms and a Poincare-Hopf type theorem for the signature

Boldizsar Kalmar

We give complete geometric invariants of cobordisms of framed fold maps. These invariants consist of two types. We take the immersion of the fold singular set into the target manif…

Interlacement of double curves of immersed spheres

Boldizsar Kalmar

We characterize those unions of embedded disjoint circles in the 2-sphere which can be the multiple point set of a generic immersion of the 2-sphere into 3-dimensional space in ter…
