‎in this paper first we define the morphism between geometric spaces in two different types‎. ‎we construct two categories of $uu$ and $l$ from geometric spaces then investigate some properties of the two categories‎, ‎for instance $uu$ is topological‎. ‎the relation between hypergroups and geometric spaces is studied‎. ‎by constructing the category $qh$ of $h_{v}$-groups we answer the question...

یک فضای مینکوفسکی ، یک فضای برداری حقیقی با بعد متناهی، مجهز به یک تابعک مینکوفسکی f می باشد. به کمک مشتقات جزیی مرتبه دوم می توان یک متریک ریمان روی این فضای برداری معرفی کرد و ابر رویه شاخص s=f-1(1)را به عنوان یک زیر منیفلد ریمانی آن در نظر گرفت هدف در این پایان نامه مطالعه میدان های برداری آفین روی فضای برداری است. که بطور همزمان نسبت به متریک فانک وابسته به ابررویه شاخص نیز آفین هستند. یک ک...

We present a new framework for rendering virtual environments. This framework is proposed as a complete scene description, which embodies the space of all possible renderings, under all possible lighting scenarios of the given scene. In effect, this hypothetical rendering space includes all possible light sources as part of the geometric model. While it would be impractical to implement the gen...

in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...

Square or geometric Kufic (also known as banna’i) developed from the Kufic script and consists of repeating vertical, horizontal, and parallel geometric units on a geometric network called a grid. Due to its unique visual characteristics and its close association with architecture, it is very promising for use in contemporary arts. This paper presents a research on contributing factors to...

an idea of fuzzy reexivity of felbin's type fuzzy normed linear spaces is introduced and its properties are studied. concept of fuzzy uniform normal structure is given and using the geometric properties of this concept xed point theorems are proved in fuzzy normed linear spaces.
