In this part we will use a purely mathematical approach to derive transformation equations for relative movement, without using physical realities. In part 2 we will exercise the received New transformation equations using a physical approach to find the relation between coefficients and eventually to obtain the final form of the Armenian transformation.
We need to use a
dimensional
approach which will best describe our existence. Let us describe an event of
the moving particle in the inertial system
by
and in the uniform moving inertial system
by
,
where
and
are
the local times and
and
are the radius vectors of the moving particle. Relations between these radius
vectors with respect to two inertial systems in general can be represented in
the following way.
![]() |
Three vectors
,
and
or
,
and
are
not coplanar, therefore the resolution of radius vectors
and
in
those three directions are unique.
Transformations of the local time
and
in
general can be constructed from infinite scalar terms as showing below:
![]() |
Since the local time and space in the inertial systems are
homogeneous and isotropic, therefore time-space transformation must be linear
in respect to the local time and radius vector, and that can only
happen when the first power of time and radius vectors are involved. Besides
that, the other terms that contain the power of
vanish
as well, because we assume that the inertial systems origin coincide (
) at
.
Therefore in the local time transformation equations
we keep only the first two terms.
To calibrate the transformation equations coefficients, we use a universal
constant - boundary velocity
,
which by the second principle of relativity has the same
value for all the inertial systems.
Finally, as a
dimensional species, we need to solve the following system of equations.
![]() |
According to the first principle of relativity, all laws of
physics, including transformation laws, must be the same in all inertial
systems. Therefore all numerical coefficients in the transformations
must be equal to each other.
![]() |
Coefficients
and
are not numerical quantities and the first principle
of relativity doesn't apply for them and therefore they are not equal
to each other. We need to find a transformation law for them as well. These
time-like coefficients we will call real time and for the simplicity
and physical-meaning purposes we denote them as:
![]() |
Finally, according to the third principle of relativity, we can obtain the simplest transformation equations when:
![]() |
Substituting primed values from
,
and
into
the transformation equations
we
get:
Straight transformation
![]() |
Inverse transformation
![]() |
We need to be very careful, because in these transformation equations the
real times
and
are
not the physical local times of the inertial systems. In general, we
need to assume, that they can be a function from both local times
and
and therefore we need to find those relations as well. All other coefficients
can be constants or they need to be dependent on relative velocity
only.
To find the limitations of this coefficients, we need to approximate the
New transformation equations
and
when
,
and then they need to coincide with the Galilean transformation equations as
shown below.
![]() |
And
![]() |
Transformation coefficients according to
and
need
to satisfy the following limitations.
![]() |
One more thing is clear, if we are looking for a new time-space
transformation, different from the Galilean transformation, then on
top of the coefficient limitations
,
they must also satisfy the following condition:
![]() |
To derive the New transformation equations, first we need to use only, as we have mentioned already, pure mathematics without limitations and then, if necessary, to use realms of the physical realities.

Equating
and

Equations
and
are
expressing the relations between real times
and
into local times and radius vectors in the same inertial system, and
vice versa relation as well.
![]() |
Substituting values
from

and
from
the first equitation of

we
obtain relations between real times
and
into

and
only.
![]() |
Not all received equations are independent. For example, equations
can
be derived from the equations
using transformation equations
and
,
also relation
.
For our convenience we need to denote
![]() |
When we have only one relative velocity, for simplicity purposes instead of
using
we
use just
.
When we have multiple inertial systems we then use
,
,
,
and so on.
If we substitute
and
in
the second system of equations
and
then using the third system of
we obtain the following limitations between coefficients:
![]() |
Inertial systems with real times
,
which transformed according to
and
radius vectors
,
which transformed by
and
, are
the genuine components of the event. Also if we denote the real zero
components of the event in a four-dimensional time-space as:
![]() |
Then the New transformation equations expressed by the real time or by real zero components become:
Straight transformation
![]() |
![]() |
From transformations
and
we obtain an invariant expression calling it real interval
and denoting it as
and we can express it by a real time or by a real zero component as
shown below.
![]() |
Any set of components
which
transforms in a similar way to
and
, also
the distance between two events which depend on time and on radius
vector only and expressed by
,
will be called a four-vector.
From the above definition 1 it follows that the real interval
in
can
be dependent on time and radius vector of the event only, if the coefficient
is
a constant. This is the first crucial result. Coefficient
is a truly universal time-space constant characterizing the medium of
time-space or the moving particle.
![]() |
Another important consequence following from the real interval
expression
is that it is a monotonic increasing value, or more correctly, a
strictly monotonic increasing value. Because, if there is no spatial
movement at all, the real time is flowing nonstop and therefore the
real interval
only
increases. Therefore, we can implement and define the idea of absolute
time or universal time for the event.
Using a real interval
expression
we
define the absolute time of the event, denoting it
as
,
which is "flowing" by the boundary speed
and it is also invariant and strictly a monotonic increasing
value. Absolute time
and
it's differential is shown below.
![]() |
Absolute time
doesn't
have a singularity problem like the Lorentz transformation
proper-time, but it has a real time characteristics. From
we
can obtain the expression for real time and it's differential:
![]() |
To express the New transformation equations
by local time
and
, we
need to insert real time values
and
from
into
radius vector expressions
and
,
also using notations
we
get.
Straight transformation equations become:
![]() |
Inverse transformation equations become:
![]() |
Transformation equations expressed by local time
and
in
case of approximation of
need
to coincide with the Galilean transformation equations, as we've already
stated, and that can only happen, when in addition to the conditions
,
and
also
exists the condition:
![]() |
From the transformation equations
or
we
get the invariant expression for the event, which we will call the local
interval and denoted as

![]() |
By four-vector definition in section
,
the interval must depend only on time and radius vector of the event, and will
never be the function of the relative velocity.
Therefore, the coefficient in the formula of local interval
need
to satisfy the following condition:
![]() |
Therefore the invariant local interval expression
becomes:
![]() |
From the condition
follows
that the coefficient
in
has
a sign of
and
in general,we assume, that it is a real number. Because at this moment we do
not know the sign of the coefficient
,
therefore we cannot talk about absolute time derived
from
.
Here we can talk only about proper-time, denoting it by
. This
proper-time and it's differential is:
