Cardinal invariants connected with adding real functions by Francis Jordan Real Anal. Exchange 22(2), 696713. In this paper we consider a cardinal invarient related to adding real valued functions defined on the real line. Let F be a such a family, we consider the smallest cardinality of a family G of functions such that h+G has non-empty intersection with F for every function h. We note that this cardinal is the additivity, a cardinal invarient previously studied, of the compliment of F. Thus, we calculate the additivities of the compliments of various families of functions including the darboux, almost continuous, extendable, and perfect road functions. We briefly consider the relationship between the additivity of a family and its compliment.

Colloquium Announcement Department of Mathematics West Virginia University for Thursday, March 11, 1999, at 3:45pm in 315 Armstrong Hall (Tea and cookies begin at 3:00 in coffee room.) Professor Tomasz Natkaniec Gdansk University, Poland limits of sequences of real functions The talk will be suitable for a general audience. Students are strongly encouraged to participate. Abstract Most important classes of real functions are not closed under pointwise limits. (See e.g. continuous functions or Baire class one functions.) But what happens if we consider longer sequences? Then we obtain results that depend on some additional set-theoretical assumptions.

Continuous function From Wikipedia, the free encyclopedia. Topics in calculus Fundamental theorem Function Limits of functions Continuity Calculus with polynomials Differentiation Product rule Quotient rule ... Stokes' Theorem In mathematics , a continuous function is one in which arbitrarily small changes in the input produce arbitrarily small changes in the output . If small changes in the input can produce a broken jump in the changes of the output, the function is said to be discontinuous (or to have a discontinuity As an example, consider the function h t ) which describes the height of a growing child at time t . This function is continuous (unless the child's legs were amputated). As another example, if T x ) denotes the air temperature at height x , then this function is also continuous. In fact, there is the dictum in nature everything is continuous . By contrast, if M t ) denotes the amount of money in a bank account at time t , then the function jumps whenever money is deposited or withdrawn, so the function M t ) is discontinuous. For continuity as it is used in topology, see

That is the standard way to extend the power function, defined by induction, to a continuous function, by identifying the square root with the "one-halfth" power, etc. Unfortunately, a nice way to do this for "tower" rather than "power" is not apparent: 2T1=2, 2T2=4, 2T3=16, 2T4=65536, but what could 2T(3.5) possibly be?

ANALYTIC and HARMONIC FUNCTIONS Section 3.1 Differentiable and Analytic Functions Does the notion of a derivative of a complex function make sense? If so, how should it be defined, and what does it represent? These and other questions will be the focus of the next few sections. Using our imagination, we take our lead from elementary Calculus and define the derivative of f at , written Definition ( Complex Derivative ), Page 93. The definition for the derivative of f(z) at is similar to that for real functions provided that the limit exists. When this happens, we say that the function f is differentiable at . If we write , then definition of derivative can be expressed in the form If we let w=f(z) and , then the we can use Leibniz's notation for the derivative: Illustrative Example for Page 93.

Next: NARROW-BAND FILTERS Up: One-sided functions Previous: FILTERS IN PARALLEL POSITIVE REAL FUNCTIONS Two similar types of functions called admittance functions Y Z ) and impedance functions I Z ) occur in many physical problems. In electronics, they are ratios of current to voltage and of voltage to current; in acoustics, impedance is the ratio of pressure to velocity. When the appropriate electrical network or acoustical region contains no sources of energy, then these ratios have the positive real property. To see this in a mechanical example, we may imagine applying a known force F Z ) and observing the resulting velocity V Z ). In filter theory, it is like considering that F Z ) is input to a filter Y Z ) giving output V Z ). We have The filter Y Z ) is obviously causal. Since we believe we can do it the other way around, that is, prescribe the velocity and observe the force, there must exist a convergent causal I Z ) such that Since Y and I are inverses of one another and since they are both presumed bounded and causal, then they both must be minimum phase. First, before we consider any physics, note that if the complex number
