On Subgroup Topologies on Fundamental Groups

Autor: Rashid, M. Ab dullahi, Jamali, N., Mashayekhy, B., Pashaei, S. Z., Torabi, H.

It is important to classify covering subgroups of the fundamental group of a topological space using their topological properties in the topologized fundamental group. In this paper, we introduce and study some topologies on the fundamental group and

Small Loop Transfer Spaces with Respect to Subgroups of Fundamental Groups

Autor: Pashaei, S. Z., Mashayekhy, B., Torabi, H., Rashid, M. Abdullahi

Let $H$ be a subgroup of $\pi_{1}(X,x_{0})$. In this paper, we extend the concept of $X$ being SLT space to $H$-SLT space at $x_0$. First, we show that the fibers of the endpoint projection $p_{H}:\tilde{X}_{H}\rightarrow X$ are topological group whe

Goodness of fit test under progressive Type-I interval censoring

Autor: Nadeb, H., Torabi, H., Hamedani, G. G.

In this paper, we propose several statistics for testing uniformity under progressive Type-I interval censoring. We obtain the critical points of these statistics and study the power of the proposed tests against a representative set of alternatives

Some results in quasitopological homotopy groups

Autor: Nasri, T., Mirebrahimi, H., Torabi, H.

In this paper we show that the nth quasitopological homotopy group of a topological space is isomorphic to (n-1)th quasitopological homotopy group of its loop space and by this fact we obtain some results about quasitopological homotopy groups. Final
