In formal language theory, a grammar is noncontracting (or monotonic) if all of its production rules are of the form α → β where α and β are strings of nonterminal and terminal symbols, and the length of α is less than or equal to that of β, |α| ≤ |β|, that is β is not shorter than α. A grammar is essentially noncontracting if there may be one exception, namely, a ruleS → εwhere S is the start symbol and ε the empty string, and furthermore, S never occurs in the right-hand side of any rule. None of the rules of a noncontracting grammar decreases the length of the string that is being rewritten. If each rule even properly increases the length, the grammar is called a growing context-sensitive grammar. (Wikipedia).
Determining the negation of a hypothesis and conclusion from a statement
👉 Learn how to find the negation of a statement. The negation of a statement is the opposite of the statement. It is the 'not' of a statement. If a statement is represented by p, then the negation is represented by ~p. For example, The statement "It is raining" has a negation of "It is not

What are Non-Classical logics?
Some of the general classes of non-classical logics I touch in this videos are linear logic, relevant logic, modal logic, many-valued logics, minimal logic, paraconsistent logics and so on and so forth. Let me know if I should dive deeping into a certain scene? https://en.wikipedia.org/wi

Definition of a Surjective Function and a Function that is NOT Surjective
We define what it means for a function to be surjective and explain the intuition behind the definition. We then do an example where we show a function is not surjective. Surjective functions are also called onto functions. Useful Math Supplies https://amzn.to/3Y5TGcv My Recording Gear ht

Active vs Passive Voice in Your Writing
Have you ever noticed how some parts of your writing work really well, while other parts aren’t so great? You can improve those dull sentences if you consider how you structure them. There are two voices in writing: active and passive. In the active voice, the subject of a sentence acts,

Learn how to identify the discontinuities as removable or non removable
👉 Learn how to find the removable and non-removable discontinuity of a function. A function is said to be discontinuous at a point when there is a gap in the graph of the function at that point. A discontinuity is said to be removable when there is a factor in the numerator which can cance

Improved contraction methods for discrete boundary value problems
This work features new mathematical research. It analyzes a two--point boundary value problem (BVP) involving a first--order difference equation, known as the ``discrete'' BVP. Some sufficient conditions are formulated under which the discrete BVP will possess a unique solution. The inno

I will discuss joint work with Hugo Parlier concerning the shortest noncontractible loops—’systoles’—in a translation surface. In particular, we provide estimates (some sharp) on the number of systoles (up to homotopy) in the strata H(2g-2) and the stratum H(1,1). We also determine the ma
