Papiya Bhattacharjee Assistant Professor of Mathematics Penn State Erie The Behrend College Title Distributive Join Semilattices , with 0 Abstract A lattice is a set L with a relation , such that any pair of elements from L has a least upper bound supremum and a greatest lower bound infimum On the other hand , a join semilattice is a set S with a relation such that any pair of elements from S has a supremum there is no infimum It is known that the study of distributive lattices is equivalent to the study of algebraic frames satisfying the finite intersection property FIP Also

    I decided to play hooky from school yesterday, so here’s the homework that was due yesterday. By around 10 AM, I had a fairly simple happenings post laid out in my head. 3 books came in during the week. Lorenz’ “The Essence of Chaos” begins fairly slowly, but I think it will be a worthwhile [...]

  • Elapsed time

    KidsMathBlog Easy To Follow Guide , Worksheets Tips For Parents Teachers About Math For Kids Elapsed time One of the most difficult subjects for primary school pupils to understand . Since it cannot necessarily be viewed and certainly not touch children often get confused when calculating exercise exercises or solve the . problem With my students , and I have found that using a timeline is the most effective method to determine accuracy Although there are other methods available e.g . T-chart , add subtract times the time it takes the concept of non-material and makes it easier for . students Take the following problem , for : example Araceli wake up at 7 : 05 am and get dressed , eat breakfast , take the bus to school . She stays in school until 3 : 45 this afternoon and finally gets home

  • Value place: whole numbers and decimals

    Updated: 2012-02-22 10:19:41
    : KidsMathBlog Easy To Follow Guide , Worksheets Tips For Parents Teachers About Math For Kids Value place : whole numbers and decimals One of the most important foundations of any child studying mathematics and an accurate understanding of the value of the place . Unfortunately , many adults were taught that the figures were just numbers” and represent amounts from various things for example , number 2, may represent 394.0 apples 2394 or posters 2394 Seldom we learned that each number in number from them to billions-represented hundreds of separate quantity , even more rare that we learned to be able to visualize each value the same place . Unfortunately , this lack of education deep great difficulty for many adults when faced fractions and decimals and exponents . etc UT elementary

Abstract The purpose of the talk is to exhibit the structure of the ring as a direct sum of ideals formed from idempotent elements of the ring . nbsp The only prerequisite is the definition of a group . nbsp I will show that the ring of integers mod n can be viewed as a module over itself , which means that any submodule is also an ideal of the ring . nbsp A nice implication of this is that any element r in the ring can be written in a unique way as the sum of q elements , where q is the

    Let’s see. It’s been a relatively slow week, mathematically. You can see that a group theory post went out last Monday… I had said last Saturday morning that it existed only in my head. Clearly I succeeded in taking it from stage II through stage V… but I didn’t have time for much else. I’m [...]

    Today, on St. Valentine's Day, I'm launching a series of podcasts which I call "Inspired by Math." In these podcasts I explore the two-part burning question - How is that some people are inspired by Math and how can we bottle that? Keith Devlin gave me the gift of 32 minutes of his insights. More [...]

    Here's something quite remarkable, from the Princeton University Press Blog: Twenty-four years ago a 2,392-city example of the TSP was solved in a 23-hour run on a super computer to set a new world record. This same problem now solves in 7 minutes on an iPhone 4 thanks to a free app: Concorde TSP Solver! [...]
