we prove that, given any compact metric space X,

there exists a residual subset R of H(X), the space of all home-

omorphisms on X, such that if f 2 R has a totally chain-transitive

attractor A, then ...

Persistence of herbicides in soil is a major concerning world issue due to their negative impacts on environment and human health. Laboratory and bioassay experiments were conducted to evaluate the effects of municipal waste compost (MC) and sheep...

Topological data analysis in an approach to use topological techniques for analysis of datasets. Persistent homology is one of the main tools of topological data analysis used for reducing the dimension and
complexity of the data sets, and also...

Persistent homology is a concept in topological data analysis used to reduce the dimensionality and
complexity of the data sets, and also to determine topological features and delete noises. In this talk,
unfolding process is simulated...

We consider the two parametric family of perturbed Lienard equation . In fact we show how the periodic orbit of the Lienard equation can persist under the two parametric perturbation. We answer this quation by useing the Melnikov theory....
