Abstract
Corrected claims. With the M2 product and the standard rapidity–weighted sum, SSM has: (i) an abelian group under ⊕; (ii) a commutative monoid under ⊗ on all pairs and an abelian group under ⊗ on the subset m ≠ 0; and (iii) exact distributivity of ⊗ over ⊕. With the operational zero-canonicalization, SSM is a commutative ring with unity (1, 0); on m ≠ 0 it forms a commutative group under ⊗ (hence a field with these operations). The collapse phi(m,a) = m is a ring homomorphism to the classical reals.
Definition (symbolic numeral and operations)
An element is a pair x = (m, a) with m in R and a in (-1, +1). Let u = atanh(a) and choose gamma >= 0 (default gamma = 1).
Addition (⊕ / oplus, streaming rule). For two terms:
(m1, a1) ⊕ (m2, a2) = ( m1 + m2 , a_sum )
u_sum = ( |m1|^gamma * u1 + |m2|^gamma * u2 ) / ( |m1|^gamma + |m2|^gamma )
a_sum = tanh( u_sum )
Zero-canonicalization: if m1 + m2 = 0 (exact), return (0, +1).
The same (U,W) accumulator gives associativity for any finite multiset.
Multiplication (⊗ / otimes, M2 default).
(m1, a1) ⊗ (m2, a2) = ( m1 * m2 , a_prod )
u_prod = u1 + u2
a_prod = tanh( u_prod )
Collapse. phi(m, a) = m.
Additive channel (⊕): abelian group
- Closure.
R × (-1, +1)is closed under⊕. - Associativity. Exact for any finite multiset via the
(U,W)accumulator. - Commutativity. Symmetric in the arguments.
- Identity.
0_S = (0, +1)(operational canonical representative of the zero-class). - Inverse.
-(m, a) = (-m, a)andx ⊕ ( -x ) = (0, +1)by zero-canonicalization.
Conclusion: (SSM, ⊕) is a commutative (abelian) group.
Multiplicative channel (⊗, M2): monoid on all pairs; group on m ≠ 0
- Closure. Magnitudes multiply classically;
uadds, soa = tanh(u)remains in(-1, +1). - Commutativity/associativity. From real multiplication and rapidity addition.
- Identity.
(1, 0)sincetanh(atanh(0) + u) = a. - Inverses (nonzero magnitudes). For
m ≠ 0,(m, a)^{-1} = ( 1/m , -a ) (m, a) ⊗ ( 1/m , -a ) = ( 1 , 0 ).
Conclusion: on S* = { (m, a) : m ≠ 0 }, ⊗ is an abelian group; on all pairs (including m = 0) it is a commutative monoid with the absorbing element (0, +1).
(Contrast) M1 (direct alignment product) would be (m1*m2, a1*a2). It is non-normative here: it lacks stable inverses when a = 0 and can require explicit clamps to keep a in [-1, +1].
Distributivity (exact with M2 and standard weights)
Let w(m) = |m|^gamma. For any x, y, z:
x ⊗ ( y ⊕ z ) = ( x ⊗ y ) ⊕ ( x ⊗ z ).
Magnitude channel. Classical distributivity:pi_m( x ⊗ (y ⊕ z) ) = m_x * ( m_y + m_z ) = m_x*m_y + m_x*m_z.
Alignment (rapidity) channel. Write u_x, u_y, u_z and w_y = w(m_y), w_z = w(m_z).
Left-hand side rapidity:
u_L = u_x + ( w_y*u_y + w_z*u_z ) / ( w_y + w_z ).
Right-hand side rapidity (weights scale by |m_x|^gamma, which cancels):
u_R = ( |m_x|^gamma * w_y * (u_x + u_y) + |m_x|^gamma * w_z * (u_x + u_z) )
/ ( |m_x|^gamma * (w_y + w_z) )
= u_x + ( w_y*u_y + w_z*u_z ) / ( w_y + w_z )
= u_L.
Hence distributivity is exact for the M2 product paired with the rapidity–weighted ⊕.
Ring and field statements
- With the operational zero-canonicalization,
(SSM, ⊕, ⊗)is a commutative ring with unity(1, 0). - On
S* = { m ≠ 0 }, every element has a multiplicative inverse, soS*forms an abelian multiplicative group. Together with the additive group,(SSM, ⊕, ⊗)behaves as a field under these operations.
Collapse homomorphism
phi : SSM -> R given by phi(m,a) = m satisfies:
phi( x ⊕ y ) = phi(x) + phi(y)
phi( x ⊗ y ) = phi(x) * phi(y)
phi( (1, 0) ) = 1, phi( (0, +1) ) = 0.
Thus phi is a ring homomorphism; restricting to S* gives a group homomorphism under ⊗. SSM is a conservative extension of R.
Interpretation
- Think of
⊕as an associative, commutative aggregator with scale-aware weightingw(m) = |m|^gamma. - The M2 product
⊗keeps alignment bounded (uadds) and guarantees stable inverses form ≠ 0. - Exact distributivity ensures the symbolic algebra aligns with classical algebra on magnitudes while transparently transporting stability.
Summary
Abelian group under ⊕; commutative monoid under ⊗ on all pairs and abelian group under ⊗ on m ≠ 0; exact distributivity of ⊗ over ⊕; ring homomorphism phi(m,a)=m. With these, SSM forms a commutative ring with unity (1, 0) and behaves as a field on the nonzero subset.
