命题公式(proposition formula) 由命题常元、命题变元、逻辑联结词组成: 命题常元(proposition constants):表示具体命题及表示常命题的p,q,r,s等和t,f。 命题变元(proposition variables):以“真、假”为取值范围的变量,仍用p,q,r,s等表示。 命题公式简称公式,采用大写A,B,C等表示。 1.2.2 命题公式的定义...
(); // Matrix vector operations - return a new Vector $AB = $A->vectorMultiply($X₁); $M = $A->rowSums(); $M = $A->columnSums(); $M = $A->rowMeans(); $M = $A->columnMeans(); // Matrix norms - return a value $‖A‖₁ = $A->oneNorm(); $‖A‖F = $A-...
Discrete Mathematics is a branch of mathematics that deals with how sets of numbers are arranged. It can also be used to study prime numbers, factorization, and non-repeating random sequences. There have been many uses for discrete mathematics in the modern world. Some of these uses are when...

In this paper, we consider approximating expansions for the distribution of integer valued random variables, in circumstances in which convergence in law (
In the case of the case hZ in the setting of discrete ML-kernel (AB) [30] and discrete exponential kernel [34], it was noticed that the monotonicity factor depends on the step h. However, for the discrete power law case [31] the monotonicity factor is independent of the step h. Sinc...
