It covers the topology of metric spaces, continuity, connectedness, compactness and product spaces, and includes results such as the Tietze-Urysohn extension theorem, Picard's theorem on ordinary differential equations, and the set of discontinuities of the pointwise limit of a sequence of continuous functions. Problems for Section 1.1 1. This volume provides a complete introduction to metric space theory for undergraduates. A brief introduction to metric spaces David E. Rydeheard We describe some of the mathematical concepts relating to metric spaces. Given a metric space X, one can construct the completion of a metric space by consid-ering the space of all Cauchy sequences in Xup to an appropriate equivalence relation.

Deﬁne d: R2 ×R2 → R by d(x,y) = (x1 −y1)2 +(x2 −y2)2 x = (x1,x2), y = (y1,y2).Then d is a metric on R2, called the Euclidean, or ℓ2, metric.It corresponds to But examples like the ﬂnite dimensional vector space Rn was studied prior to Banach’s formal deﬂnition of Banach spaces.

In calculus on R, a fundamental role is played by those subsets of R which are intervals. Remark. Treating sets of functions as metric spaces allows us to abstract away a lot of the grubby detail and prove powerful results such as Picard’s theorem with less work.

India, a nation of 1.2 billion people, is the most varied market in terms of food in the world, cheers to regional differences in cultures, lifestyles and preferences. Today’s consumers select those restaurants or brands that understand them and provide them with the experience they seek. India is a price sensitive country and good bargains and promotions catch consumers’ attention. This trend is seen across consumers categories. For Indians getting valued brands for a lesser price enhances their dining experience and is a motivating factor for them to be more loyal to the restaurants or brands. With the changing habits, there is an increased preference for convenience and eating out. According to various industry experts, nuclear families and bachelors are turning towards takeout, home delivery and semi-prepared meals (ready-to-eat/ ready-to-cook meals) as these are lower cost and also time saving options. According to a recent report by Financial Express Online, this is one important reason why FMCG companies like Nestle, Parle, or PepsiCo have not changed the prices of their products like Maggi, Lay’s and Parle-G for nearly a decade now. Harish Bijoor, Founder Harish Bijoor Consultancy Inc, told Financial Express Online, “These price points become memory points as well. The consumer reaches out to these packs and to an extent has an economy story in his or her mind for sure. The moment this price point is altered, even by 50 paise, there is a jarring effect in the minds of the consumer, retailer, and indeed the entire trade channel.” The Internet economy is bringing convenience in our lives that consumers want everything at the touch of a button, which led to the emergence of food-delivery platforms in India. The online food ordering business in India has boomed in last two years with the entry of several platforms such as UberEats, Zomato, Swiggy, among others. Considering the potential in the Indian market, these platforms have been expanding foothold in India and have more than three lakh restaurants listed on them. These platforms have gained increased usage by consumers by focusing on single-serve value-meals and varied cuisines. According to RedSeer’s Foodtech Market Updates, the foodtech industry has seen an overall Gross Merchandise Value growth of close to 140 per cent in 2018, with order volumes increasing by a whopping 176 per cent on account of discounts and value deals provided by food aggregators. Keeping up with this trend in the country, a global QSR brand like Subway has introduced Chhota Sub, a 4-inch-mini submarine sandwich in four flavours for consumers who are constantly seeking value-deal options with exciting taste. Subway India in past had introduced SubWraps as a snacking product priced at Rs 49 for vegetarian options and Rs 69 for non-vegetarian options. The brand is also running ‘Sub of the Day Offer’ for its guests to have an opportunity to relish their favourite submarine sandwich at an attractive price once a week and is a popular value deal. With the rapid growth of millennials as the major consumer segment, the perception of product’s value and premiumisation has also altered. Consumers no longer consider a product premium based on just a high price tag. Globally, less than one-third (31 percent) of the consumers consider a product premium only because it is expensive. Thus, a clear demand for value-for-money is emerging amongst the younger consumers.
