A Note on Intuitionistic Fuzzy Hypervector Spaces

The notion of Intuitionistic fuzzy hypervector space has been generalized and a few basic properties on this concept are studied. It has been shown that the intersection and union of an arbitrary family of Intuitionistic fuzzy hypervector spaces are also Intuitionistic fuzzy hypervector space. Lastly, the notion of a linear transformation on a hypervector space is introduced and established an important theorem relative to Intuitionistic fuzzy hypervector spaces.Comment: 13 page

A Note on Hypervector Spaces

The main aim of this paper is to generalize the concept of vector space by the hyperstructure. We generalize some definitions such as hypersubspaces, linear combination, Hamel basis, linearly dependence and linearly independence. A few important results like deletion theorem, extension theorem, dimension theorem have been established in this hypervector space.Comment: 17 page

A Few Properties of δ\delta-Continuity and δ\delta-Closure on Delta Weak Topological Spaces

The main aim of this paper is to define a weakest topology $\sigma$ on a linear topological space $(E, \tau)$ such that each $\delta$-continuous functional on $(E, \tau)$ is $\delta$-continuous functional on $(E, \sigma)$ and to find out the relation between the set of these $\delta$-continuous functionals on $(E, \tau)$ and the set of all $\delta$-continuous functionals on $(E, \sigma)$. Also we find out the closure of a subset $A$ of $E$ on that weakest topology by the $\delta$-closure of $A$ with respect to the given topology

Tourism in Bangladesh: Present Status and Future Prospects

Bangladesh is full of natural beauty. It is surrounded by river, coasts and beaches, archaeological sites, religious places, hills, forest, waterfalls, tea gardens etc. The sundarban, Historic mosque city of Bagerhat, Ruins of the Buddihist vihara at paharpur are the three world heritage sites existed in Bangladesh among 1007.  To observe the beauty of nature, huge amount of domestic and foreign tourists visit the said places. In 2012, around six lakh  tourist came Bangladesh to visit and enjoy it’s natural beauty. The total contribution of travel and tourism to GDP was 4.4% , to employment was 3.8% and to investment was 1.5% in 2013. Bangladesh Parjatan Corporation (BPC) look after the tourism sector in Bangladesh under the ministry of Civil Aviation and Tourism. Due to some limitations, Bangladesh has failed to introduce to the tourists as a tourist destination country. The paper tries to focus on the attractive tourist spot of Bangladesh and the contribution of tourism in the Bangladesh economy. The major concern of the writer is to highlight the factors by which Bangladesh can be one of the major tourist attractive country in the world in near future. Keywords: Tourism, Economy, Impact
